Depot Movement Warning Device

DMWD (66-1016)

The Depot Movement Warning Device (DMWD) has been designed and manufactured by Trent Instruments.

The application for this device is primarily for long 10 car trains which are split up to enable each section to fit into a loco depot or workshop.

The units fit on the centre 2 carriages and are controlled using fly by wire feed from an electronic switch which is controlled from the drivers desk in the cab.

Precise control, calibration and verification makes it possible to achieve exacting customer requirements in any application.
