A Full Train on One Bench
Traction, braking, doors, HVAC, and passenger information appear to the TCMS as live subsystems, so control logic is exercised end to end without booking time on a real rake.
Every specification here is proven by our own engineers. Bacancy Systems' rolling stock team designs, populates, and tests each board in-house at Ahmedabad, backed by 16+ years of embedded engineering across EN 50155, IEC 61375, and mission-critical rail electronics. It is world-class railway technology, engineered in India and built to serve fleets anywhere.

Every hour of TCMS debugging on a real train costs track access, crew time, and schedule risk. We built the simulator so those hours happen at a desk instead: scripted, repeatable, and logged.
Traction, braking, doors, HVAC, and passenger information appear to the TCMS as live subsystems, so control logic is exercised end to end without booking time on a real rake.
The simulator speaks both the Multifunction Vehicle Bus and Ethernet-based TRDP under IEC 61375, matching the exact network conditions the TCMS will see in service.
Drop a node, delay a telegram, corrupt a data frame. The failures that take weeks to reproduce on a train take seconds on the bench, and the TCMS response is logged every time.
Every test run is a script that can be replayed after each software change, turning TCMS regression testing from a commissioning risk into a routine desk exercise.
Pair the simulator with the Bacancy Systems TCMS Unit and TRDP System Validator for a complete build-and-prove workflow from a single Indian manufacturer.
The same bench serves a new-build integration lab, a supplier acceptance test, and a refurbishment program proving retrofitted control logic, and because every scenario is a script, results stay comparable across all of them.

A TCMS simulator is a test bench that recreates the subsystems of a train, such as traction, braking, doors, HVAC, and passenger information, as simulated nodes on a train communication network. It lets engineering teams run the Train Control and Management System against a virtual train, so control logic is proven on the bench before commissioning on real rolling stock.
The simulator communicates over the Multifunction Vehicle Bus (MVB) and the Train Real-time Data Protocol (TRDP) under the IEC 61375 Train Communication Network family, so it can exercise both legacy and modern Ethernet-based TCMS architectures.
Yes. Test engineers can drop simulated nodes, delay telegrams, and corrupt data to observe how the TCMS responds under failure conditions, which is exactly the behavior that matters most for safe rail operation.
Yes. The simulator is built as the validation companion to the Bacancy Systems TCMS Unit, running hardware-in-the-loop tests against the real control computer. Paired with the TRDP System Validator, it forms a complete bench validation toolchain for rolling stock control logic.
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.
