Train maintenance is done on work positions above the ground. Therefore it requires a very qualitative solution to guarantee the safety of technicians.
Technicians are responsible for changing and replacement of "inverters" that conduct electricity from the catenary to the trainset roof.
The technical solution proposed by the Tubesca-Comabi design office in partnership with the SNCF in Lens is a tailored modular product.
A precise response to the customer's specification:
Make a fixed walkway so that agents can walk around and work on the platform. And to supply a safe work position for replacing heavy parts.
