Passenger Information Function & Features

System Module

  • This system forms an extension to the existing PA and intercom equipment as already installed on several motor coach versions, including all current 10M5 motor coaches. The system is also compatible with some 10M2 & 10M4 motor coaches. The module is installed inside the existing Amplifier.


  • The purpose of the system is firstly to keep the passengers informed of events along the route travelled. This includes welcome messages, station arrival, destination, doors open and closed, end of trip, safety messages, etc. These messages can be selected in alternative languages depending on the route traveled.


  • During the trip the system can also play music. Music can be selected according to the trip travelled and customer requirements. Further enhancement of the system can incorporate streaming from a content provider which could include pertinent messages regarding events etc.


  • The system caters for pre-recorded advertisements to be played at specific locations or at specific times of the day.

Safety and Communication Features


  • The system incorporates a cell phone interface that allows secure communication between the driver and the CTC offices. Importantly, the operator can identify with whom the conversation is taking place. At the same time the CTC office can select to make a direct announcement on the train. This announcement can also be pre-recorded.


At present the train position can be accurately recorded and monitored by authorized users at CTC or other institutions. This not only augments the present signaling system but allows the communication system to identify the exact train set or unit, position, speed and route selected. In addition events such as over-speeding can be logged. This event could trigger a SMS alert to be sent to the CTC offices. History of the routes traveled and other events can be recorded at the tracking system as well as on the train itself.
