Rail depot improves diagnostics for test benches

A maintenance depot connected older test benches so electrical teams could review faults remotely before a trainset arrived.

Challenge

Specialized benches were reliable but isolated. When a fault occurred, the few engineers who understood each bench had to be physically present.

Modibus approach

Modibus connected PLC, power and safety signals from each bench, giving engineers a secure remote view with role-based access.

Outcome

The depot reduced diagnostic waiting time and created a shared fault history across shifts. New technicians could learn from previous events rather than starting from zero.

The remote view did not replace expertise. It put the expertise in the room earlier.
