When a train's destination station is removed (via circuit conditions, schedule, or physically) a train stops instantly. Instead of stopping instantly, I expected the train to decelerate like a physics-abiding object.
Steps to reproduce:
1. Make a station with a name different from any other stations in the world
2. Make a train with that station as its only destination
3. Switch the train into manual mode
4. While the train is on its way to the station, do one of the following:
- a) Click "Remove the station" in the train's GUI
- b) Physically delete the station (this is a bit more difficult)
- c) Disable the station via circuit network
