ABSTRACT:
A fluid system for the rail brake cylinder of a highway/rail vehicle including a control valve responsive to brake pipe pressure drops to provide a control signal to a variable load relay valve assembly which provides brake cylinder pressures. The relay valve assembly maintains the rail brakes deactivated in the highway mode, provides braking pressure independent of the variable load portion for low pressure in the control valve's auxiliary reservoir, maintains a rail reservoir and rail suspension supply changed from the highway and rail supply lines, and creates an emergency condition in the brake pipe for low rail supply line and or rail reservoir pressure.
