Removes a train from the model. There are two ways a train can be removed: it can move out of the rail yard via an open-ended track, in which case
TrainDispose
should follow the last
TrainMoveTo
block that was controlling the train, or it can "disappear" from any location in the rail yard, provided it is not moving.
TrainDispose
(and not
Sink
or
Exit) must be used to remove any trains.
