ABSTRACT:
A retainer is provided for retaining a catch mounted to a first portion of a split ramp car in its unlocked position as a second portion of a ramp car exits a locking area in which it is previously locked. An arm portion of the retainer extends into the locking area and controls the operation of the retainer in response to the movement of the ramp and the locking area. A fluid coupler, automatically couples a first and second portions of a main reservoir pipe and a first and second portions of a brake pipe connected to each first and second portion of the ramp car respectively, when the ramp is in its raised and travel position. Valves in each of the main reservoir passages close the main reservoir passage when the first and second housings are separated and opens the main reservoir passages when the first and second housings are joined. An electrical coupler is also automatically coupled as the two portions of the ramp car are joined. The fluid and the electrical coupler are mounted to the respective portions of the ramp car so as to be aligned and adjust themselves with respect to the ramp car during mating.
