ABSTRACT:
A railroad crossing gate (20) is disclosed having a novel crossing arm (24) which includes a first longitudinal arm (26) member with a telescopically inserted second longitudinal arm member (28). The second arm member (28) is slideable to any one of a plurality of extendable positions and a fastener plate (100) disposed between the first and second members (26, 28) is provided for urging the second member (28) against the first member (26) in friction locking engagement. A plurality of gate lamps (38) are provided having a housing (40) which includes a channel for receiving an upper edge of the crossing arm (24). Screws (50) on both sides of the housing (40) are turned until the housing (40) is secured to the crossing arm (24) in a friction fit. Extensible cables (70) with three-pronged connections connect the gate lamps (38) to circuitry to operate the gate lamps (38) in a predetermined pattern.
