Abstract:
A system for maintaining brake cylinder pressure comprises a maintaining valve, a brake pipe, an emergency reservoir, and a brake cylinder configured to be in fluid communication with the brake pipe and the emergency reservoir. The brake pipe is configured to sustain a predetermined pressure within the brake cylinder during a brake application based on a differential between a pressure of the emergency reservoir and a pressure of the brake pipe.
