When were facts check with Heiner Geissler discussed all aspects of Stuttgart 21, and the arbitration proposal S21 + shows me that understands Heiner Geissler, the central problem of Stuttgart 21. What he has failed this is a wider audience to be understood. For this reason, I've seen compelled to write this added unusually long article.
the track and Mr Mappus try in the meantime very successful at calling the perception of voters on issues of which the protagonists accept, rating their own electorate this as less important. For example, in the past week launched the action tree pushing, noisy and trees to transplant with a lot of police and demonstrators willingly jump. By looking sloppy work, like giant air gaps between the root ball of the transplanted trees and the ground, they have brought further up to speed. The conclusion This successful policy crisis: All the speeches about trees, vehicles without exhaust filters, a train which follow the provisions of the arbitration continues, but no one talks about the stress test.
But is precisely this stress test is essential, it displays the Stuttgart 21 not just the citizens of Singapore uses, but the wine bar jugglers and Deutsche Bahn. A station in a central location that does not allow additional trains is exactly what needs the web to keep the competition at bay. From the many state coal for the planning of such an expensive, complicated words, projects, proportion give a lot of money. also expresses the path to this White Mountains from the rehabilitation of the tunnel .
Many of us have a driver's license, and tend to therefore to the rails with the eyes of a car to look at handlebar. The first thing you notice here, bars are always empty. Without seeing as this is a wrong perception, we will always keep S21 for successful planning. Unlike cars, trains leave their mark not, whether the there exists a crossover, where a fork in a road or two to merge.
In the next section is located above the roadway, down time. A box is in the horizontal direction as a km in the vertical direction a minute. Then can the Passage of a train as a line on this sheet represent. We see different moves from left to right driving. Respectively at the stops they slow down until you come across are for. Then the lines run vertically. After stop, the train continued its journey. With a frequency to meet the timetable followed by other trains.
What may not now happen on such a track. Now the one hand, the trains are not driving faster than allowed, because otherwise not guaranteed that the train remains at all in the track. Furthermore, no train shall meet. It sounds trivial but just a few days the web has proved but it's not everywhere wangles because the necessary safety equipment is missing. This is shown on the right side, where a slow shunting causes identified by the steeper line with less km per minute, a Frontalzusammenzos. Finally, a train can also remain even more poignant, because of an accident, a defect or because a passenger has pulled the emergency brake. Shown on the left side where the train is waiting below (vertical line) because the track is blocked, and the next back on it thunders.
What happens to prevent it? First, I must come back again to the experiences of readers with Cars. Each of us that a car direct must know that he needs to secure his load. And what about the two train? Now appreciate the logistics train for it there is no need. Why not? Now a train may be compared to a car or truck as good as brakes, because iron is much smoother than asphalt. Trains have therefore a much greater stopping distance and braking soft, so eliminated security and straps can. In this respect, the necessary safety distance is much larger than the car.
same time each train can also be delayed. That must be the fault of the train may not work. Can indeed always be times that a train can not depart on time. There might also, for example, a problem with the loading a child or wheelchair scales give a passenger or simply connect to the stairs next to it. To this end, there are the typical technical shortcomings of the track. From daily experience we know that the trains always have a few minutes late. A train can also be eigendlich premature? Yes, but only until the next stop. There he has to wait because other passengers would complain.
What happens if a train is delayed? I have located the items for the maintenance station on the left. Say, a passenger has a problem with walking difficulties with his luggage, the stay in the station is longer. Now the train is late, so the blue, lower graph move. What options he has now, time to make up for? First, the Schaffner try the following to make shorter stays, on the other hand, the Lockführer to drive a little faster. That is visible in the slightly shallower blue graph. The latter is of course only if the schedule is not based on driving the speed limit. Cheating is not otherwise trigger the security technology an emergency brake.
in the left side I have for some exemplary Scheduled positions located because of the safety distance and delays kept free range. The rich always 5 minutes after delays below the safety margin is growing for physical reasons with the square of speed, that is, twice the speed four times safety distance. Since this is valid but for each point of the graph must be the result plotted on the right areas.
trains run in all weather conditions, the right of the web. So even in fog, when the Lockführer not have the view of his security clearance. For this reason, there is the block signals. Which are typically at the end of a holding point. They show green when on the part of the behind the signal that no train is located, and red when there is a train. Thus, the maximum they will not potentially delayed train to the area and found the next train can enter only if the train has left the area. This results in commercial operation at the Grey rectangles that must remain free because of the security technology.
would of course also reflect the delays to be added, because otherwise it would trigger the emergency brakes and safety technology in this emerging technology by the security repressions. These are the blue areas under the gray rectangular areas. It can be seen that the design of these lines allows only one train every 15 minutes. Why does it make any sense, seemed embarrassed when someone points almost never drive do? Well, you can rail at much more transportation at a time by many scales attached to a locomotive. The capacity of a line thus depends crucially on the safety equipment. Take time on the commuter rail line from Central Station to the University to the distance of the signals. Is to see Schwabstrasse much shorter, so that trains can follow within a short driving. may be on the route to the university then only very few block signals available, so the areas are very large, so only the intended 6 trains per hour driving. The Bottom Line, the commuter trains could not go on them all!
Come we get to a timetable with Nähverkehrszügen and now has regional trains. The transport, holding in each station to know they have. Now we draw our graph below a train all the way through without stopping out. I call it ICE. It therefore accounts for the vertical parts of the graph, which represents the hold. It should be noted that the block signal has already stand some time before the passing of the train on green. Would not that be the case, the security technology on the ICE distant signals and the associated magnets would slow down as a precaution. The signal must therefore stand at the latest in green when the front edge of the safety distance of the ICE, the signal passes. That is the reason why the block signals are like train stations behind the halt trains have a minimum safety distance required.
propelled by the ICE comes on the line is moving very much faster than the Nähverkehrszug. The S-Bahn train is because it runs between the stations as soon as you as opposed to the tram which, like a car being driven on view, the security technology needs. Because of the many visits, but overall it is progressing slowly. The ICE will then fly to the travelers before him train. Since a train can not just disappear, so must the purple colored area are kept free. Is this purple area It also once again below the ICE, because subsequent follow the S-Bahn and can not bridge the gap is widening. This loss of traffic capacity is the reason why S-Bahn trains as possible get their own track.
After this introduction to the problems of scheduling, we can finally address the gist of the matter. Around Stuttgart 21 eingleissiege many sections are provided. This may be the classic single-track line, as the Western connections of the remote station or the airport east of the S-Bahn station which is to find for the ICE's use of Basel or the infamous little Wendlinger curve. A single-storey Threading on the opposite track produced but also, albeit very short, single-track line. Of these, there are still two of Wendlinger curve and a more Rohrer of the curve.
follow in the chart above, I have located two tracks. A red is the driving from left to right, and another red, is the danger from right to left. Consequently, green features are also shown, from left to right, driving, and red, moving from right to left. Outside the single-track section of the trains can pass each other on different tracks. This means that the red areas should not touch, and the green areas may not be . Touch In the single track area, I have kept the land in white, because there may of course do not touch anything . Furthermore, it should be noted that I have located only a safe distance, the area above the graph, and the delay zone, the area under the graph. The block signals from the outside once I leave here, because the new lines that no longer point way by train safety signals, but by a GPS-like system is carried out continuously. At block signals were at 250 km / h, the safety distances so large that the distant signal would sometimes take place before the main signal of the block before.
is important to understand that is fully drawn down in the road map not only the single-track piece, but all other tracks. It could be for example between the two green features on the dark purple area can take another train to the right, but the agency would be able to go anywhere the single track. This is the same as the ICE runs onto the train. Here, too much traffic volume is burned. Also created a shadow agency by the single track meet by the red train, that time which may no longer train. You have to know that this with increasing distance, as long as the route's no point accounts, also does not change. That is, these strips can go where no train, which extended to take the next big station where different routes.
This is the reason why all the advice, the station or to consider other portions alone are invalid because the trains are capable of traveling at the time because it is not coming out no more.
The problem with Stuttgart 21: These stripes meet other single-track sections and are blocking each other, because here and there and there still a Milliönchen had to be saved to the political pain thresholds at least until violating an irreversible point not. So what now have the roadmap planner do? You have to get space, sometimes simply declaratory said that trains have only up to one minute late. This is now the point where anyone who is ever track down, before falling off the chair laughing.
delays at the track so ubiquitous and inevitable as gravity, what happens when a train between one and five minutes late, but the schedule has only delayed strips of one minute? Then wait one of the trains, whichever is more important. The following chart I have shown that for the first train from left to right again. He will say after the single-track authority at a time be on the road where he should not be.
He will be including the wrong time at the next single-track authority, so he's delay does not degrade, but further delay receives and, worse still infects about security, and more moves to your exclusions. Since then passed on average delays are broken down faster than they work, the new station any more. Then either have to elaborate more tunnels are built, or the timetable to be modified, which is run much more slowly as possible so that the train drivers have enough reserves to take the delays within a very short time again. Only, why is frittered away so much money to spare for the new high-speed lines, but then when you drive slowly, just so she could in the needle tubes so be on time. In the case of the expected Verspätungslawienen will then also be the lack of platform tracks in Stuttgart main station to the catastrophic problem, because in the course of the railway system are of course route exclusions. S21 can not be built. K21 or better my alternative V21, which is characterized by the fact that much of the planning costs can be obtained.
