B61J SHIFTING OR SHUNTING OF RAIL VEHICLES (shifting vehicles in general B60S; marshalling systems B61B)
Introduced: September 1968
Description
B61J covers apparatus and methods for shifting, moving, or shunting individual rail vehicles or trains within rail yards, depots, and sidings. This includes mechanical, hydraulic, and electrical systems for coupling, uncoupling, and repositioning rail cars, as well as specialized equipment such as retarders, buffers, and propulsion devices used in marshalling operations. The classification excludes general railway vehicle design (B61D) and track-switching mechanisms (B61L), focusing specifically on the equipment and techniques that facilitate the tactical movement of rolling stock.
