Claim:
1. A pneumatic brake system for regulating the speed of a train, comprising: an electronic control board configured to receive a brake signal from a locomotive, the electronic control board configured to receive the brake signal, generate signal data, and transmit the signal data to activate a brake; an electronic control valve in communication with a brake pipe at a first railcar, the electronic control valve being configured to receive the signal data and selectively release air pressure within the brake pipe at the first railcar so as to actuate the brake; and a pneumatic control valve in communication with the brake pipe at the first rail car and configured to release air pressure within the brake pipe in response to downstream pressure changes within the brake pipe; wherein release of air within the brake pipe by the electronic control valve increases the rate of response for the operation of the pneumatic control valve; and wherein the brake on the first railcar is applied as air pressure is reduced.
