The invention relates to a sub-assembly for a searchlight signal comprising three distinct light emitting diodes and an interface module for connecting the three diodes to a controller. The interface module comprises: a light input adapted to receive a signal for feeding a light emitting diode, a first relay having an active position and an inactive position, and a second relay having an active position and an inactive position, such that: when the second relay and the first relay are in the inactive position, the light input is fed to a first LED, when the first relay is in the active position, the light input is fed to a second LED, and when the second relay is in the active position, the light input is fed to a third LED.

Sub-assembly for searchlight signal, and associated assembly

A lost motion apparatus for adapting a typical in-tie switch machine, designed for use with interconnected switch points, to be used as an in-tie machine for moving the movable V-point of a movable point frog assembly.

Movable point frog switching assembly

A control mechanism for moving switch points on a railroad track, having a drive screw driven by a motor, a traveling block moving along the drive screw to position the switch points, an end stop on the drive screw for limiting movement of the traveling block, a hand crank for manually turning the drive screw, and a torque limiting clutch on the hand crank.
