This was reported back when the Budd M3 became available for LIRR in TSW 2020. Pressing the Alerter (Circle on PS4) causes the train to slam into emergency braking. However, in TSW 2 it is even more annoying. If you exit the pause screen or the map screen using the Circle button, the pause screen or map screen are exited, but the alerter is also pressed, which causes the train to slam into emergency braking. I more often than not exit the pause screen and map screen by pressing Circle. It’s engrained in my muscle memory, so now I keep triggering the emergency brakes in the Budd M3.
