The end of the car with the handbrake is the B end. This diagram shows how locations are identified on a typical freight car. The basic locations are generally the same on all freight cars. ![]() 3ĥ Part 1: Freight Car Locations A-End Understanding the locations on a freight car is basic to identifying and repairing items requiring attention or finding defects on the car. In this manual the various types of brake rigging is covered showing the relationship of the levers, rods, pins, brake cylinders, slack adjusters and handbrakes have on the overall operation of a typical rail car. This design eliminates a lot of the rigging necessary for conventional rigging by having the brake cylinder attached directly to the truck rigging assembly. Other car designs use truck mounted brake arrangements. Conventional rigging today uses automatic or self adjusting slack adjusters to do the same job of manually adjusting the brake rigging. To ensure there was minimal slack in the brake rigging and the piston travel stayed consistant, the carman or inspector had to adjust the rigging though moving the manual adjuster on the brake rigging assembly. Early conventional rigging arrangements used rods and levers attached to the underside body of the car with a manual type slack adjuster. This design has the brake cylinder in close proximity to the control valve and other brake devices. The majority of coal cars (open top hoppers or gondolas) are equipped with body mounted brake assemblies mounted on the end of the car. Body mounted or conventional brake rigging on freight cars uses a body mounted brake cylinder located approximately in the center of the car. Piston Travel Review Exercise 2Ĥ Introduction Understanding the operation of the brake rigging provides a carman with the ablility to make repairs that will ensure the rigging components function as designed, proper braking forces are acheived and there is reduced possiblity of personal injury or property damage while working on the equipment. ![]() Special Brake Arrangements Part 3: Brake Rigging Adjustments Lever Angularity 2.
