A pressure equalization valve arrangement for a rail brake system comprises a hold valve 2 and a membrane vent valve 3, each having a control chamber. The hold valve 2 and vent valve 3 are piloted by a respective solenoid valve, 6,10. A further solenoid valve 9 is connected to the control chamber of the vent valve to allow the pressure across the vent valve membrane to be equalised with the brake cylinder pressure in order to decrease the pressure difference across the membrane. This results in an improved vent time.
