The trips for rear facing signals are suppresed when the road is set in the
opposite direction.  This means they are kept lowered.  A trip hitting a train
stop in the wrong direction will not cause it to trip, however, if the train is
travelling fast enough (above about 40 km/h) the trip will bounce back and
operate itself.

It is worth mentioning that unless the trip arm is lowered, the train will not
power.
