A hand brake control system for a rail vehicle hand brake having a release trigger. The system includes a cylinder (10) for activating the release trigger of the hand brake and a source of pressure (14). A first valve (30) selectively connects either the source of pressure at a first input (32) or a second input (34) to the cylinder (10) at an output (36). A second valve (50) selectively connects either the source of pressure or exhaust to the second input (34) of the first valve (30) at the output (56) of the second valve. The first valve (30) is a manually operated valve and the second valve (50) is an electro-pneumatic valve. Linkage allows actuation of the first valve from at least two locations about the vehicle. 50 EMERGENCY 28 RESERVOIR ) EX 38 26 22 F 6 52 32 30 lo0 58 343 YLNE SUPPLY 20i,0 46 -+wCYLINDER 4 0-
