Every Node, Every Telegram
The validator watches both cyclic Process Data and on-demand Message Data across the consist, so nothing on the TRDP network moves unobserved.

TRDP System Validator: Prove the Train Network Node by Node
The Bacancy Systems TRDP System Validator checks Train Real-time Data Protocol communication across the whole consist, confirming that every node sends the right telegram at the right time per IEC 61375. Designed, populated, and tested in-house in Ahmedabad, it gives integration teams hard evidence that the train network is ready for service, before the train is.

Why Bacancy Systems Validator
Certainty for Every Telegram on the Train
Train network faults hide in timing, addressing, and stale data, the failures no visual inspection can find. We built the validator to surface them with evidence: captured traffic, timing statistics, and pass or fail results engineers can act on.
01 02 IEC 61375 Conformance Focus
Telegram timing, ComId mapping, and addressing are checked against the Train Communication Network standard, turning conformance from an assumption into a report.
03 Finds the Silent Failures
Missed deadlines, stale data, and misrouted telegrams rarely announce themselves in service. On the validator they show up in minutes, with the capture to prove it.
04 Reports Engineers Can Act On
Every run produces logs, timing statistics, and pass or fail results, the documentation acceptance testing and safety cases actually need.
05 Completes the Validation Toolchain
Paired with the Bacancy Systems TCMS Simulator and TCMS Unit, the validator closes the loop from control logic to network behavior, all from one Indian manufacturer.
Where It Runs
From First Power-On to Fleet Acceptance
The validator earns its keep wherever a TRDP network has to be trusted: the first power-on of a new build, the acceptance test after a retrofit, and the depot visit chasing an intermittent fault nobody can reproduce.
Pre-service network validation on new builds
Acceptance testing after TCMS and network retrofits
Troubleshooting intermittent train network faults
Supplier and subsystem integration testing
Regression checks after network software updates

FAQ
TRDP System Validator: Frequently Asked Questions
A TRDP system validator monitors and verifies Train Real-time Data Protocol communication on a train network. It captures live traffic, checks telegram timing, addressing, and data integrity against IEC 61375, and reports whether every node on the consist is communicating correctly.
It covers both cyclic Process Data and on-demand Message Data as defined in IEC 61375-2-3, so both the fast periodic traffic that runs the train and the event-driven messages between subsystems are verified.
Yes. Because the validator captures traffic continuously with timing statistics, faults that appear once a week in service can be caught, timestamped, and traced to a specific node or telegram on the bench or in the depot.
Yes. The two are built as a pair: the simulator generates realistic subsystem traffic and the validator proves that traffic is correct, giving engineering teams a complete bench validation toolchain for rolling stock networks.
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.
