How come the rolling stock handbrakes are not used? Is it not the case that in the real world when you uncouple from your rake of wagons should you not secure them from rolling away
When you uncouple from a rake of wagons, their brake pipe vents to atmosphere and their brakes slam on. If those wagons are going to be moved again soon, there's no need to do more. However, the air does slowly leak out of the system over time, so if the wagons are going to stay put for, say, overnight, then handbrakes are set. Usually one brake for every 10 wagons, unless the grade is steep or they are unusually heavy.
TSW's Physics system is strange but ill try to explain it. when you sit in a loco drivers seat you sorta bind yourself to a train via hoping into a the seat wagon physics kick in iow Swaying and weight physics when you couple a wagon that wagons gets this property as well if you uncouple it they disable but its also unable to move on its own no matter the grade it hard to explain if you were to have a giant line of cars (eg 200+) and you bind yourself to the train it kicks in the physics of them all and it can cause lag so that's why AI and Lonely wagons don't need there handbrakes on, don't sway, and are not effected by weight because their physics are disabled
