Abstract
A railroad brake sensing apparatus particularly suitable for handbrake sensing has a sheave wheel/bellcrank bracket which is slotted to allow the wheel/crank axle to move from a first position when the chain is under tension and the brake is applied; to a second position when the chain is slack and the brake is off. A sensor is placed to detect when the wheel/crank is in the second position. The brake sensing apparatus is easily adapted to be used with other forms of brake actuating force and placed with other moving members of the brake rigging.
