32-axis under-bridge maintenance vehicle

Multi-axis lifting system that raises a rail vehicle for maintenance with every lifting point held in synchronization.

Every train carries an RFID identity tag on its windscreen — the way a car carries a toll transponder — and from that identity the system follows where the train is, what it is doing and what maintenance it owes. Around a thousand people work in it at the same time; inside the maintenance depots they are reached on their phones.

Drive, positioning and safety electronics for a platform that carries maintenance crews across a large roof structure. Its passengers are people, and that is what sets where the safety case starts.
