ETS – Emergency Trip System Monitoring

The Emergency Trip System (ETS) is used for monitoring trip conditions by Trip Push Buttons (TPB) at multiple locations along the rail track. Trip Push Buttons are used for tripping the two adjacent substations and deenergizing the feeding power of a rail track section in case of an emergency. A phone is used to communicate directly with the dispatch control center and report an emergency in the track.

The system monitors TPB coil voltage, current trip status and the general health of the ETS equipment installed along the track. Bright blue LEDs always show the location of the ETS unit along that section and a flashing amber LEDs shows train drivers the presence of a work crew on a track section.

The status conditions of each ETS unit along the track and the fact that personnel are present on that section of line are relayed to the nearest ePAQ data concentrator for local display (via touch screen HMI) as well as relaying this information to the central SCADA Operations Center.
