Abstract

A point rail is shiftable transversely on an upper face of a rail base plate between an engaged position bearing on a longitudinally extending and fixed stock rail and a disengaged position spaced transversely of the stock rail. A roller assembly has a mounting plate securable to the rail base plate, a roller support pivotal about a support axis on the rail base plate, a roller carried on the roller support, and a spring biasing the roller upward with a predetermined spring force into a lift position with the roller projecting upward past the upper face for supporting the point rail on the roller. Thus this assembly supports the point rail and, in the engaged position, presses it against the support cleats and the stock rail and it is an integral part of one of the rail base plates.
