I have no idea. If this is real time control that could mean you keep running the motors in the switch long enough to damage something. Or maybe you go past the end of travel switch signal without reading it, the switch turns off and you never stop... There are a lot of ways real time systems can fail.

You are correct that 10ms is well within the margin of error for safety stopping a train, but it may be out of the margin for some subsystem in the control.
