So I was wondering...when you change cabins, what kind of brakes should you leave in release and what kind of brakes can you leave in full service?! I've noticed with the British Rail Class 43 for example that you can leave the train brake in full service (on one cabin) and still move the train forward through the other cabin. But am I doing it right?! Or should I leave it on release?! Can someone explain this to me please?! Thank you in advanced.
