Abstract

A two-way safety trip is placed at selected locations along a railway track to demarcate a safety zone within which the travel of a railway vehicle is stopped upon entering the zone and is permitted to continue upon leaving the zone, the safety trip including a bracket for attachment to the track and a trip member selectively mounted upon the bracket in alternate mounting orientations for serving at either boundary of the safety zone.
