Passenger Information System

Passenger Information System

This system is designed to facilitate passengers with information on present and next halting station through audio and visual displays using GPS in sub urban trains like EMUs (Electrical Multiple Units), MEMUs (Mainline Electrical Multiple Units) and DEMUs (Diesel Electrical Multiple Units). Unlike the present system of rotating the destination board (Head Code) by motor man, this system uses LED based Head Codes with necessary information like destination, via stations, number of cars etc.
