I believe it's normal that the pressue overshoots 5 bar even just a little bit. it should be fine though, or can you not move by that?
Don't use Quick Release - it's actually overcharging the brake pipe and is used for another purpose (releasing stuck brake cylinder valves)
If i keep holding the brake throttle on "release very quick", the white needle stops over 5.0/5.1 bars and the train is not manage to start
That’s normal. You’ll probably never get 5.0 in real life. Stay away from any release position on the brakes if you don’t know exactly what you’re doing. Only use the ‘running’ position. You’re overcharging the brakes which creates all sorts of problems if you don’t know how to handle it.
Thank you for the information, but i would like to understand how it works and to learn to manage them
Well, essentially, ‘release’ lets you put more pressure into the brake pipe than usual. There are different ways this works, but the end result is more or less the same. At this point, you might be asking yourself “Why should I want that?” There are two answers to this and we’ll start with the more complicated one. The problem with real life is imperfection. As already mentioned, different driver’s brake valves on different locos operate at different pressures due to wear and tear etc. One might only have 4.9bar in the pipe while another one has 5.1bar. If you couple a wagon operating at 5.1bar to a loco that only gets up to 4.9bar, you won’t be able to release the brakes. In this case, you can overcharge the brake pipe (usually to 5.5bar). This is called Angleichen (to make the same) in German. That way, the brakes are reset in a way. The excess pressure will be slowly bled off over time (as quickly would apply the brakes). However, you mustn’t apply the air brakes while the pipe is still overcharged! If you do that, you set the overcharged pressure as the normal release pressure. That’s why the brakes get stuck if the overcharge is handled improperly. You need to wair until you’re back to ~5.0bar before doing anything with the air brakes. The other reason you might want to overcharge is to save time. I don’t know if modern locos even let you do that, but older Bundesbahn locos did. After e.g. a penalty brake application, it can take a long time to release all of the brakes. Here’s where the Füllstoß (fill burst) comes into play: You overcharge the brake pipe quite a lot, but the pressure drops again as the rest of the (empty) brake pipe gets filled up. Same conditions apply - no messing with the brakes until you’re back to a stable ~5.0bar. Again, I don’t know if you can even do this anymore on newer locos and it’s only intended for when the brakes are applied hard (full brakes or penalty brake). That about sums it up. As you should see now, there’s really no reason to mess about with it in TSW. It won’t do anything for you and will force you to stay away from the air brakes for quite a bit.
You mean if you apply the brakes while overcharged and they get stuck? You need to overcharge the brakes again. Then don’t mess with them until they’ve gone back down to 5.
