Abstract
The present method operates an electrically controlled pneumatic (ECP) brake system that includes a system controller and a plurality of ECP devices on a train, in a semi-active mode between an active mode and an in active mode. The method includes setting the system controller to the semi-active mode if the ECP brake command is release; and setting the released ECP devices to the inactive state by the system controller when entering the semi-active mode. The ECP devices are set to an active state and to apply the brake by the system controller in response to an ECP brake command of apply. The ECP devices are reset to release and then to the inactive state by the system controller in response to an ECP brake command of release.
