MVB / TRDP Module: The Train Communication Gateway

The Multifunction Vehicle Bus (MVB) is the serial communication bus defined in the IEC 61375 Train Communication Network family. It connects subsystems within a rail vehicle, such as traction, braking, doors, and HVAC, and has been the workhorse of train control networks for decades of rolling stock.

The Train Real-time Data Protocol (TRDP) is the Ethernet-based communication protocol standardized under IEC 61375 for modern train networks. It carries both cyclic process data and on-demand message data between rolling stock subsystems over standard Ethernet infrastructure.

Fleets rarely modernize all at once. A gateway lets proven MVB subsystems keep running while the consist network moves to Ethernet-based TRDP, so operators retrofit the TCMS and network without replacing every subsystem supplier at the same time.

Yes. The module is engineered to EN 50155, the international standard for electronic equipment on rolling stock, covering the temperature, humidity, shock, vibration, and EMC conditions of rail service.

Every board is designed, populated, and tested in-house at Bacancy Systems' facilities in Ahmedabad, India. It is a Make in India product backed by 16+ years of embedded engineering experience.
