Abstract
A computerized locomotive control system receives as inputs electrical signals representing automatic and independent braking control signals from controllers and pipe pressures and has a computer for determining, from said input signals, electrical signals representing desired braking and pipe pressures. The computer in the lead locomotive uses the independent application and brake pipe pressure to control the brake cylinder pressure except where the independent application and release brake pipe has been tested as a fault or during the initial buildup of the independent application brake pipe. In this instance, independent application and release controller position is used to control the brake cylinder pressure.
