Train stop
Part of a railway signalling system, a train stop, trip stop or tripcock (sometimes called a tripper) is a train protection device that automatically stops a train if it attempts to pass a signal when the signal aspect and operating rules prohibit such movement, or (in some applications) if it attempts to pass at an excessive speed.
Usage examples of "train stop".
The great virtue of the Seventh Saint, besides the price of its drinks and its nearness to Old Law Farm, a train stop away, was its wide front windows, nearly floor to ceiling, in which as in a shadow-box or on a movie screen the life of the street outside passed.
The man at the train stop said there was one coming in in about half an hour, but he didn't know where it was going.
