train

driver who throws schwenna before Upon departure, the 23-year-old checks the systems, particularly the brakes, we check if the brakes apply and release because we have several brake systems, one electric and the other pneumatic, we have to check both.

I activate the pneumatic manual control and on this screen I can see each car, the power units are here, we are. sitting here that all the brakes are applied and that the electric brake drive works perfectly and that the signal changes to green the driver can leave the room with the warning whistle first I check if the whistle works and I also warn the personnel of the station because As you can see, it's quite difficult to see people here, that's why I also have to leave very slowly because it's very dangerous because the train doesn't stop immediately within two seconds.

This transfer movement is considered a maneuver movement. This means that the maximum speed allowed is 25 kilometers per hour. However, the train driver must be very careful when entering the station. The difficulty in the entrance lane to the intermediate stop is that I have to control the speed. I have to brake but I also have to be careful. For passengers, today we are lucky that they are not too close to the edge because often, when a train arrives at the other platform, people walk on the far right and do not see me arriving with the train and the suction effect is already .

There, even at 25 kilometers per hour, while the on-board restaurant is quickly stocked and emptied and unloaded on the platform, Casting Schwentner hands the ice to the train driver, Lutsyecker, who will drive the train to the castle with our selector preset speed that serves for automatic control of the engine and brakes. I set the allowed speed the preset speed selector basically works like a cruise control system in a car while leaving the Munich train station the 24 year old has to maintain a maximum speed of 40 kilometers per hour then Lotiekel can accelerate if the sign in front here now shows wait stop, so in one kilometer we have a red sign, we have to stop in front of it, we also have to recognize this sign, if we don't, the automatic brake is applied, well, the ahead signal has changed to clear, so we can accelerate again, but only for a moment because the ice is approaching the pause train station and it is not on the usual track, so now the traffic controller calls us at 882.

Good morning. You are asked to reduce your speed considerably again. platform thanks ciao, now you have told me that we will drive on the platform, that is why we have to go at 60 kilometers per hour, normally we would have traveled the analysis at 130 kilometers per hour, the train driver can accelerate again to speeds above 160 kilometers. per hour no longer runs visually now I have the signals in the driver's cabin the signals on the open line no longer apply to us they can be turned red as long as the signals here in the driver's cabin allow us to run we will run now we have a clear line of 9 900 meters around 10 kilometers and we can do 200 kilometers per hour in the traction unit lotziecal is the boss but further back in the cars cargolina regal says what's up good morning ladies and gentlemen welcome aboard the Deutsche Bahn Ice to Hamburg Altona We hope you have a pleasant journey just to let you know about our onboard catering service today.

We can recommend our delicious breakfast with crumbled eggs and freshly brewed coffee. Why not pay at our restaurant or bistro on board? visit, we hope to see you dear friends, as train manager carolina regal is responsible for communicating with passengers and the traffic control center as to whether the train is on time and passengers can reach their connecting trains, e.g. , the 29-year-old young man. is also responsible for onboard security for ticket inspection and technology in the passenger area during our ticket inspections we also take a look in the bathrooms to see if the flushing mechanisms are working, if the water in the sink is working and We also check for any fair evaders in the bathroom because that is usually their favorite hiding place.

She also has to make sure the onboard restaurant is replenished. I have a request for you. Great, for which train station is a castle preferable. If you can handle it well, I will take care of it. that's good thank you she easily takes care of the order using her cell phone the ice now travels at about 230 kilometers per hour the routine for lucieca the first time I drove over 200 kilometers per hour in the driver's cabin it was pure adrenaline because simply There is no Compared to a car, if you wanted to brake now you would need about two kilometers.

Now speeds up to 250 kilometers per hour have become completely normal for me, you just get used to it and up to 300 kilometers per hour the adrenaline kicks in. play again because this is not something that happens every day ice with a maximum speed of 330 kilometers per hour the flagship train of Deutsche Bahn its history began in 1985 with the intercity experiment it was succeeded by ice one five of these trains arrived to the new Wilhelmshur Castle railway station from various directions in the spring of 1991. The era of high-speed train travel had begun in Germany. I would like to wish you, your team and all German railway workers a safe journey at all times and now I will change.

The red button to green the ice was the pride of the nation. Finally, the country had caught up with the TGV operated by its neighbor France. In the following years, the Ice2 and Ice3 followed with various technical specifications such as the Icet, a train with technology. of inclination that allowed it to circulate at relatively high speeds even on winding routes, while the first ICS showed their age more than a billion passengers and the ravages of time had left their traces the ice tank at the Munich central station the hall 400 meters long has the capacity to accommodate Up to 12 trains What is called a restart program is being carried out here for ices 1, 2 and 3.

This means that the trains, some of which have already been in operation for 25 years old, will receive a visual and technical facelift on the field in this campaign. is run by christina dordich among others she is a vehicle technology engineer during the restart we had the opportunity to take our ice vehicles out of service for one to four days so that we had time to repair all comfort effects e.g. , these worn headrests just don't look very good anymore and we want to restore them. Technicians check each seat. Back. Headboard. Armrest. the strips of the floor in the first class section the toilets in the ice3 have recently proven to be a real nuisance not only do they no longer look very attractive some of them are also technically defective after many years of operation the old washed hatches suffered seriously damage and some of them no longer work properly they can no longer close the toilet paper no longer stays properly in them which was simply no longer acceptable to our customers that is why they are leaving the bathrooms should be more attractive thanks to the movies that the employees of a specialist The company is gluing fake mosaics with a floral design on the walls, but the film also has a very practical benefit: they are washable, have anti-graffiti protection and can be cleaned very quickly.

They have a laminator, a transparent laminate and that also protects the design, so they are protected from scratches and they are washable, they are very good, so anyone who wants to immortalize themselves here with pens or sprays can think again, the film has to be a little hidden so that it cannot be removed immediately so it is installed behind the mirror and the accessories now all that remains is to cut the excess film and the bathroom is finished with new sink flaps and a disinfectant dispenser the difference compared to before It's like night and day, in addition to the restart work, major repairs are also being carried out at the Munich ice warehouse.

Metallurgist Alois Elmower and his colleagues have a complicated job ahead of them on the ice with tilt technology the spring brake on this set of wheels is defective and we have to change it to do this we have to remove the entire set of wheels to be able to get to the spring brake to replace it the spring brake also has a parking function like the handbrake in a car alois el mawa now moves a shifter, a type of hydraulic lifting platform under the set of wheels, which is used to raise the set until it no longer touches the

rails

once all bolts and connections have been loosened.

Alois Elmawa removes what is called the track bridge, which otherwise gets in the way during the withdrawal, supports are placed under the bogey and the set of wheels is lowered so that the 1,600 kilo piece cannot roll. Metal workers have to secure it with wedges. Alois Elmar now lifts the wheelset and moves it. get it out from under the train your colleagues can now get to the faulty spring brake and dismantle it once the old spring brake has been removed we install the new one once it is installed we install the brake pads again and then we reinstall our driven set of wheels and when everything is finished the train undergoes a brake test and then can return to the track the ice one that the driver of the train luciacl drives today from munich to the castle is now passing through several tunnels in terms of visibility in the tunnel that has It must be said that the train driver sees little or nothing, so the main beams of the previous generation vehicles are not at all the best and it must be said that if there are people on the tracks, for For example, you can't see them at all on the most modern ice, the entire tunnel is illuminated, ladies and gentlemen, we are now arriving at Wildwood Central Station, please exit the train on the left.

Train manager Carolina Regal has to be very attentive at train stations, especially right before the train leaves. Now I have to make sure everyone has gotten on and off, that's complete and now we're all ready to go, so let's go. Carolina Regal wants to check the tickets of the passengers who have just boarded the train, but she can't. To do so at the moment, the buggies should not be here because they are entry and exit doors, so they are also escape routes and have to remain clear. Now we have to find out who the buggy belongs to and then we will do it.

I have to make sure it's removed. The owner of the stroller is quickly determined, but the problem persists, so the lady does not know how to fold the stroller. I'll go get my colleague's help and then we'll see if we can. I can do it, this is an advertisement. Could the on-board bistro companion come to car 5? Her colleague arrives two minutes later, what's happening? We have to take a look and see if we can fold the stroller the lady doesn't know how it works and I thought we could do it together if no one else can do it we will manage it somehow in just two moves the employee collapses the stroller let's put it in that compartment and then you're out of the way. some space here while carolina regal now has to inspect the tickets.

The train driver Lucieca doesn't have much to do, at least at first glance, in railway circles we are often called straight drivers because we don't have to drive but we have to pay attention to many other things, for example braking, if there are dangers on the track and we also have to take into account the timetable, which now says to slow down, so we are now slowing down the four-folder Fulda Central train station. In the driver's cabin arrives a model from the 411 ice an icet series with tilting technology, which can also travel at high speeds even on winding routes, coming from Berlin in the opposite direction.

Ricochernetsky, 50, is sitting in the driver's cab along with a trainer he works for. He Berlin and transfers trains from the train allocation depot to the train stations. He is not yet authorized to drive on ice with tilt technology, but now he wants to get his license for it at the training center.Deutsche Bahn in Fulda, among other methods. future ice train drivers. they are trained here in the fribert krauss simulator one of the instructors is preparing the simulator to operate the main component of the simulator is the afb the automatic control of the engine and brakes the train driver can use it to set the maximum speed the traction adjuster practically like the accelerator pedal in a car, the driver's brake valve, that is, the brake, the ebula, our schedule, our technical display, four malfunctions and here below is our dsd, the driver's safety device, the train driver has to activate it every 30 seconds, it is used to determine if the train the driver is still healthy in terms of health and if he does not operate it the train stops after 30 seconds hello rich good morning freebert how are you well rich chernetsky Now you have four days to practice operating the ice in the simulator then you have to take the test and then you go upstairs please again okay I'll be in touch okay?

It's stressful because you can only simulate and experience all the failures and contingencies that do not arise during normal operation in a simulator like this. It often happens that in the normal operation of the vehicle everything is fine, I would say in about 90 of the cases. but here in the simulator you can find everything that can go wrong in theory in the vehicle with the vehicle and many things are going to go wrong today, so rich, you can take charge of your vehicle, okay, your train number is 9300 and we are traveling. from the folder to what works fine 9300 that is correct, the simulator runs in real time on a schedule of 32 minutes and we go here in the folder we can leave the train station at 100 and then at 140 kilometers per hour my technician guide says no Malfunction, that's very good, but that's not still the case, so the screen now shows me how fast I can go at 200. up to 160 kilometers per hour, the maximum braking distance is one kilometer, the signaling systems are located accordingly if the train is running.

At more than 160, the driver will no longer be able to stop in time when he sees a red signal. This is solved by the so-called continuous automatic control system of train circulation, which shows the driver a red signal before he himself can see it. If the train driver does not react, the system automatically intervenes, so now we are driving With the train's continuous automatic operation control system, the LZB will now load the traction motor due to excess temperature, one of the transmission systems will stop working for a while. some time malfunction malfunction and a malfunction has just occurred traction motor excessive temperature measures no measures required continue traveling with reduced motive power in this traction unit that means we are driving with 70 power very rich, if that is present for a long time, you can report it to your traffic control center yes, I was about to do that, I was just thinking that can't do any harm yes, hi, this is 9300, the correct answer overall, apart from the uncertainty about whether the incident should be reported to the traffic control center, so the next fault that I will upload will not be displayed on your screen, but you have to react by yourself.

Oh damn breakdown, Chernetsky must have made some kind of mistake on the ice1 on the trip from Munich to Hamburg. Train driver Lutsyeckel is familiar with situations where you are simply perplexed or even helpless. The worst situation I have had was children playing in the area of ​​the track, they were playing with a ballast. I quickly activated the emergency brake, but I have to admit that I wouldn't do it. It wouldn't have been enough if they hadn't walked away from the track if they hadn't registered my attention whistle, you really start to sweat, so it makes you very nervous because you have no control over it, basically the only thing you can do is watch, you can.

You just have to step on the brake and hope that the vehicle stops on time. It's almost 12 noon. The on-board restaurant is preparing for lunch. The three railway employees in the kitchen are very busy during rush hour. 80 meals per day hour, so here is the order for 21. pork cheeks with cabbage and salad with chicken breast and balsamic dressing, well, here are the three components of braised pork cheeks, potato patties with pointed cabbage and pork cheeks, this is prepared food. everything precooked now it's just warmed up I put them in the steamer here they have to stay there for 15 minutes and then they'll be piping hot so what else was there chicken breast?

The advantage of this catering system is that it is very fast and the quality is the same in each train we can guarantee the same product with the same quality in each train and it is presented in the same way so that each guest recognizes it immediately before they I can present my food I will just wash the dishes for first class potatoes soup is ok, it still needs a little more time the menu in first class is similar to the one in the restaurant it is also the same in terms of prices meanwhile the cabbage empanadas and the pork cheeks are ready sometimes it is a little problematic when we go through the switches the train wobbles it is difficult to present everything well so that it looks very good some food occasionally spills over the edge of the plate and can no longer be used that's completely normal so you just have to fix it up a little bit do something new that's It's totally normal to stand with your legs wide apart and try to balance things out a little bit.

You see, I'll put the salad on the plate. Now there are two people sitting at the table and we want to make sure that the food is always served. at the same time 20 minutes after ordering the two guests the food arrives at the same time as it should a salad with chicken breast and a stewed pork cheek with cabbage thank you enjoy your meal along with a quarter of a liter of wine red that comes to 32 euros 30. Back in the driver's cabin on the ice, so now we approach the Castle train station. We still don't have permission to enter.

In two kilometers we have an expected stop that is exactly one kilometer in front of the platform. The brake is applied so that the train does not come to a complete stop the automatic brake control system has been deactivated we can now enter a target speed of 100 kilometers per hour for luzieco the journey ends at the Castle train station another The driver of the train will cover the remaining section to Hamburg Altona. My colleague is already waiting, so we will prepare everything for delivery. The delivery also includes a verbal report on technical problems, if they have occurred during the trip.

There are no problems with the train. Good trip Lutz now has a one hour break and will then drive another ice back to Munich. The Deutsche Bahn training center in Fulda Rico. Chernetsky is still practicing on the simulator. He wants to get his license for Icet. Ice with tilt technology managed. Well, with the first malfunction, the trainer fleet bet that Kraus loaded into the simulator for him now, however, the training program will become more demanding. The instructor establishes an emergency stopping point on the track using the continuous automatic control system of the train's progress. The emergency stop of the lzb and the lzb could mean that a train is still five or six kilometers away and the driver sees something on the opposite track.

He has not recognized the emergency stop, so his train is automatically braked by the system the simulator leans forward the train stops in a tunnel this time the 50 year old man immediately calls the imaginary traffic controller by radio this is 9300 the train has just been broken down by the lzb what are the readings on its screen stop and 100,000 hertz flashing the computer says it went through an emergency stop of the lzb is that right yeah okay listen I'll find out what's going on I'll get back to you right away okay okay the hardest thing is recognize the situation that is developing, that is, when the system says malfunction, recognize the malfunction process and do not forget anything. as well as the driving operating procedure, continuing to monitor the route and this multitasking is exactly what is needed in the simulator.

Yes, something unknown probably happened. You will receive an order from me so you can continue. Fine, thanks. See you in theory. The trip can now. continues in theory malfunction malfunction I want the brakes to be released now first perplexity then recognition the speed limiter is still at zero well when you are doing all this for the first time finally the train starts moving again after traveling for three more minutes it arrives in the target verts book, so we did it, the grueling exercise in the simulator is followed by the report, so rich that we ran for the emergency lzb style, yes, what were you thinking?

Well, first I was a little upset because I didn't immediately recognize that. It was an emergency stop from LZB because I hadn't experienced it in a long time in real life. Something like that doesn't happen often. You will recapture all these little things. Yes, I'll get used to it and then everything. will be fine trust that it will pass the test the icet with tilting technology the ice is a success story every year 250 trains transport around 80 million passengers however the history of the ic has also been marked by several setbacks the most bitter of them was the train accident in eschedu on 3 june 1998 the ice wilhelm conradrenkin derailed and crashed into the central pillar of an overpass 101 people lost their lives 88 were seriously injured the nation was in mourning the cause of the accident the breaking of a the Deutsche Bahn rolls The necessary consequences were drawn from Escher.

The rubber sprung wheels were no longer installed and the maintenance intervals were changed. Wheels and axles are no longer inspected periodically, but on a mileage basis, wheels after 288,000 kilometers and axles every 20 to 30,000 kilometers, depending on ice. series on this ice the axles are going to be checked with ultrasound today the axles are comparable to the axles of a car to rule out errors during ultrasonic inspections the measuring instruments themselves are checked before use this is done in test axles that contain several faults the verification is complete and now I have to determine whether the specifications, all the test faults appeared at first glance, it seems that the inspection sounded correctly, all the faults are there, but I have to check it again precisely in detail, the verification detailed shows that the ultrasound scanner detected all faults in the test well.

Now the verification on the ice can begin. The inspector is the warehouse specialist. Dieter Kneeps has placed an adapter in the well and inserts the ultrasonic test probe through it. He moves forward and scans every millimeter of the shaft for hairline cracks, wear and deformation. Data from individual probes are shown to the inspector on the monitor. These red lines that you can see here and that are displayed on the screen are the so-called geometric indications and are caused by the transitions of the roof ring seat wheel seat free seat brake disc seat transmission the blue line this is where my scanner the ultrasonic inspection takes about 20 minutes per shaft or shaft the spindle will look at the individual probes to see if any irregularities occurred during the inspection there are no findings the inspection is fine so I can conclude the inspection this will be followed by another 20 wells that the detox neeps have to inspect today in the past deutsche ban concentrated its ice traffic mainly in the big cities it neglected the provinces that deutsche ban intends This can be changed with a major high-speed line construction offensive that will cost 10 thousand millions of euros.

The transport project of German unit 8 aims to improve transport connections between East and West and between North and South, traveling from Berlin to Munich on ice. In just four hours one of the largest Deutsche Ban construction sites in Germany is located in Franconia, between Erlangen and Bamberg, 10 kilometers long, a lot of heavy machinery and 400 workers in one of the sections in which the ice roads They must cross the regional railway line through bridge structures. More space is also needed due to the four-way widening. The extension is only possible on the right, since the highway passes on the left. dita hilbig, the head of construction supervision, supervises this gigantic project.

Our problem here is this slope that is in danger of slipping. and could endanger the entire railway line, so we had to place four rows of foundation piles one meter 80 in diameter 20 meters deep in the ground. The holes for these 300 concrete pipes are drilled by this 180-ton drilling machine, but something in the way is stuck. dita hilbig, who is in a hurry with her work, speakswith the technicians, they explain that oil has leaked and they assume that one of the sealing rings is defective, now you have to check if the rings are worn, otherwise the entire system no longer works. works and then we have to repair it after several checks with measuring instruments, it is clear that the repairs are going to take some time, so unfortunately we have some minor damage the mechanical parts are broken the parts cannot be delivered until this afternoon or tomorrow tomorrow and we probably won't be able to continue drilling until tomorrow, this puts even more pressure on us because the work must be finished in four weeks, otherwise the entire construction project will be in jeopardy.

Another bottleneck at one of Deutsche Band's largest construction sites is Brighton Gusbach a A new railway station is being built here and the line through the community needs to be extended, a difficult and expensive task because the houses are located to the right and left of the line, that is why reinforced concrete foundation piles must also be installed here, the problem here was the large excavation extended from the original two to four tracks because the houses are quite close to the railway track, We had to change the profile as follows from the original two-way to four-way in this box section and we had to install them vertically. here there are a total of 5,000 foundation piles in a length of 800 meters purely assembly line work the next hole being drilled has a diameter of 90 centimeters the drilling head devours the stone and the earth an endless conveyor inside the tube The drilling system transports the excavated material upward, where it then falls outside to protect residents and workers from excess dust.

The outside of the drill pipe is covered after about 10 minutes. The depth of eight meters is reached. Now a pump transports the concrete into the well. through a hose through the upper end of the drill pipe which is slowly drawn out during this finished process while the drilling rig is already addressing the next hole an excavator removes the waste material from the last hole which is now filled with concrete along To the reinforcement a steel mesh cage is inserted which must be placed exactly vertically and centrally in the hole filled with concrete with the reinforced side marked in green pointing towards the slope.

First we drill the holes separated by gaps when the concrete hardens these gaps will be closed with additional holes drilled so that we have produced a continuous pile wall, as you can see there, they are called overlapping pile walls, within five months the trains will run through here about 40 kilometers south towards Erlangen. Road construction is already in

full

swing. Here 4.5 tons of ballast are needed per day. meters, one of the tracks of this section is almost finished, the sleepers of the second track are being placed every day, 1,500 of them must be placed on the ballast bed with a separation of 60 centimeters from center to center of each of the concrete sleepers. prestressed weighs about 200 kilograms, there are four prestressing tendons that significantly increase the bending resistance of the sleeper.

The prestressing tendons are prestressed to about 50 tons on the right and left of the crumbling, then the concrete is poured and once the concrete has reached a certain strength the prestressing tendons are separated if these prestressing tendons are not within The sleeper could break in the center due to the load of the train here on the outside where the rail is and then there is a risk of derailment. The workers surrounding the foreman Thomas Doletsich have little time and work in two shifts, they have to travel 900 meters per day and must work as precisely as possible when placing the individual sleepers, it is important that they are aligned to make life easier for our colleagues who install the rails later if they are not aligned, our colleagues have to adjust each sleeper again with levers, etc., and to avoid them having to do this and to stay on schedule, the preliminary work must be completed exactly every time a few hundred meters of sleepers have been installed the construction train gives way to the layers of rails arrive with a excavator that can also run on the track, on the one hand, more high-speed lines and, on the other hand, trains that have already been in operation since 1991.

The time has come for a new ice: the ice4 is already waiting in the wings and It differs from its predecessor in several ways: three cars were always coupled to form a fixed propulsion unit, meaning that only three or four cars could be added to expand the train with ice4 the individual power units are grouped into individual carriages on a self-contained drive unit, so we can achieve various train lengths very flexibly, this means that individual carriages can also be added to the ICE4 carriages are also longer and there are fewer coupling points which means more space for passengers with This train we also focus on energy efficiency and aerodynamic design.

An example of this is the fairing here on the end cars on the heads, whereby aerodynamically efficient fairings have been installed leading to a significant reduction in air resistance. and rolling resistance and help reduce energy consumption by up to 30 percent the ice is manufactured by siemens, but employees of the db system technic subsidiary of deutsche bahn are also participating in today's race and will carry out tests today safety on behalf of siemens We will be testing a wheel skid protection system that is comparable to the ABS system in a car. To do this we use soap found in water tanks and applied from the inside out, which then forms a slippery film on the rail.

We want to see if the wheels lock. During braking, the electromagnetic rail brakes are additionally used for emergency braking. Testing can now begin. The two trained test drivers, Haina Albert and Ulrich Baum, are sitting in the driver's cab. They brake at different speeds, sometimes with and sometimes without soap solution in front of the vehicle. wheels, we are sitting here in the first multiple unit of the ice4, it is about a year and a quarter old and has been used for test drives for the last nine months, as you can see the interior is covered for various tests and to prevent the interior .

To prevent props from being destroyed, we also balance the train with various weights and simulate different weight conditions so we can really test each scenario. Emergency braking will be carried out at 170 kilometers per hour and will be activated in the passenger compartment without soft soap on the rails. The ice4 takes about 55 seconds to stop from 170 kilometers per hour. The measuring station is located in a carriage in the center of the train the braking data is collected here among other things you can see the temperatures of the brake discs here here you can see the forces of the dynamic brakes the electric brakes you can see the rotation speeds of each set of wheels here you can see the brake cylinder pressure here the relevant signals are then processed and, among other information, the braking distance at the other end is obtained in this case it is 1.6 kilometers a good result the next brake test will be carried out with soap smooth on the rails at a maximum speed of 250 kilometers per hour back to the construction line for the transport project of the German unit 8. north of Erlangen the railway laying is now ready to start on the high-speed line with an excavator that can also travel on the track the individual rails are 120 meters long and weigh 7 tons although they are made of steel they seem as flexible as spaghetti and now the other side is A space of one or two centimeters is always left between the ends of the rails.

These are two fish baits that connect the joints of the rails so that construction trains can pass over them and the load distribution secures the joint enough so that the ends of the rails do not slide. folded, the rail is now secured on one side, on the other side it remains free so that high and low temperature expansion can take place there inside the fish baits and the rail is still guided, the workers then secure the plate of fished with a nut so that it cannot be loosened now the screwing machines come into play first loosen the nuts and then push the sleeper clamps onto the base of the rail before tightening the nuts again to a torque of 180 Newton meters the bolts They are greased there are two reasons for this, firstly, for bolting because the torque is reduced and secondly, to permanently seal the bolt hole so that water cannot get in and frost or similar things can cause the crossbar to crack. break Some of the sleepers have moved while the rails were being laid.

Workers have to use levers to push them back 60 centimeters apart while the tracks are already in place. A series of operations still need to be completed before the Icee can pass here at 230 kilometers per hour. The rails are now firmly connected to the sleepers. the track panel is complete, the next operation is to completely balance the area approximately up to the top of the rail, then we use a tamping machine that lifts the sleepers and repacks ballast under them so that the final position is reached with a position target of approximately two millimeters, once the rail has reached its final height, here the joint is welded and we have a continuous welded track and the rail can run over the Deutsche Bank.

For the construction of new buildings and the extension of existing ones, strict noise protection regulations have been imposed. The high-speed lines so that the neighbors do not fall out of their beds when the ice passes through them are aluminum elements that here on the side of the track are perforated with rock wool in the middle to absorb the noise, which means that The walls do not reflect the noises of vehicles or wind from passing trains. Its self-contained cassette with a rigid center so that the high suction and wind pressure tensions of the ice can be absorbed.

The new 15,000 horsepower ice4 now You have to carry out your next brake test between Volsberg and Standal and you have to do it at the maximum permitted speed of 250 kilometers per hour. To test the wheel skid protection system we mix, the so-called wheel skid protection system is being tested, comparable to the anti-lock brake system of a car. water with mild soap and spray it in front of the drive axles if this wheel slip protection system does not work, the braking distance is longer, then the wheels lock and practically scrape the rail when stopped and that causes flat spots on the rolling surface. so 2000 meters 1000 measurements operation spring operation attention and ready automatic braking the wheel skid protection system seems to be working Trained test pilot Ulrich Baum, who drove the first Ice One in 1991, is satisfied.

The Ice4 has a very innovative braking system, both pneumatic and electric. terms and can certainly be described as excellent. Yes, of course, the direct brake system is also viewed subjectively positively by the driver because its handling is very, very fast and very, very direct. Can test manager Andrea Steve also confirmed the experienced machinist's impression. we have the brake cylinder pressures and the pressure is reduced and increased again due to the wheel slip protection system and here we have the speeds of the individual wheelsets where you can see that the wheelsets are sliding, this It means that they are turning a little more slowly than In the end, the vehicle is moving, it can be said that the slip should be neither too high nor too low and that is precisely what the braking systems have achieved.

If the remaining tests are equally successful, the ice4 will continue the success story of these high-speed vehicles. trains
