A brake cylinder piston travel indicator for monitoring an amount of piston travel in a brake cylinder assembly in a railway braking system is provided. The railway braking system includes a brake beam and a brake cylinder piston within the brake cylinder assembly which is in engagement with an end of a brake cylinder force transfer lever. The brake cylinder piston travel indicator of the invention comprises a rod member which is rotatably secured to and extends substantially parallel with at least a portion of the brake beam. A member is provided which associates the rod member with the cylinder force transfer lever and is capable of transferring a rotational force to the rod member. This rotational force is caused by activation of the piston in the brake cylinder assembly. At least one indicating device is provided which is engagable with a first end of the rod member and is capable of responding to the rotation of the rod member and indicating an amount of travel of the piston during activation thereof in the brake cylinder assembly.
