Pressing WASD in a train sets it to manual

[Ingolifs]

This is just a small quality of life improvement.
It is often cumbersome having to set a train from auto to manual and back while sorting out a jammed train. However, there are circumstances where you want to be in a train and keep it automatic.

The player makes their motive clear when they use any of the WASD keys to attempt to drive it. Setting it to manual when pressing these keys would be quite useful. As far as I can think, there are no edge cases where you'd want to press these keys and keep the train automatic.
