Abstract
A computerized locomotive control system receiving as inputs electrical signals representing automatic and independent braking control signals and a computer for determining, from said input signals, electrical signals representing desired equalization reservoir pressure, desired independent application and release pressure and desired actuating pressure. Electro-pneumatic valves controls the pressure in the equalization reservoir, on the independent application and release pipe and as the actuating pipe in response to the desired pressure signals. A electro-pneumatic valve for the control reservoir of the locomotive brake is controlled by the computer in response to pipe pressures. The computer provides penalties and interlocks electrically.
