Description
Coach Guidance Display Boards (CGDB) indicates the location of coaches in a particular platform. The CGDBs are connected in a Daisy Chain sequence, where even if one of the boxes fails or removed for maintenance, the others will work independently. All the CGDBs are individually connected to the Main Data Hub from where they receive their data. Individual board are used to display the position of a coach in corresponding platforms like S1, S2, GEN, D1, A1 etc. This enables the passengers to easily identify their coach or wait for the train on the platform where their coach will be halting.
