What is electronic locking in the railroad
ür open, passengers out, passengers in, door closed. A process that you can see every day at our train stations. The perfectly coordinated interplay of technology and electronics, however, is largely invisible to you. And opening and closing alone is not enough. An ICE door also ensures that you do not notice any driving noise or the external weather. Our infographic explains in a simplified form how the door of an ICE is constructed and how it works.
Get in and out safely and comfortably thanks to complex technology
The door leaf alone weighs 92 kilograms. Opening them by hand is quite a feat. So that you don't break a sweat when getting in and out, the door of an ICE is equipped with many electronic helpers. These are coordinated via the electronic door control. If the gear motor receives the signal from it, it begins to turn the locking shaft and thus releases the four locks on the door. The door leaf is then pivoted outwards via a joint and moves along the guide rail into its end position. The closing process works on the same principle, only in the other direction. For your safety, on the right outer edge of the door, rubber-framed metal strips are attached, which stop the closing process with an electrical impulse if, for example, a hand is between the frame and the door.
Protection from noise and weather
At top speeds of up to 300 kilometers per hour, you would normally hardly understand your own word on the ICE due to the noise of the train. The temperature inside the train would also fluctuate greatly without the special ICE door and would be dependent on the weather. The occupants are protected from noise and the weather by a 4-centimeter-wide insulation made of foamed plastic, which is located between the outer and inner panels of the door leaf.
As you can see, an ICE door like this can do much more than just open and close. So the next time you get on an ICE, watch out for the whirring of the geared motor or the “clacking” when the latch is released. You now know what's behind it.
