A pressure equalization valve arrangement for a rail brake system includes a hold valve and a membrane vent valve each having a control chamber. The hold valve and vent valve are piloted by a respective solenoid valve. A further solenoid valve is connected to the control chamber of the vent valve to allow the pressure across the vent valve membrane to be equalized with the brake cylinder pressure to decrease the pressure difference across the membrane. This results in an improved vent time.
