FRANCE: RATP has ordered an electro-diesel track geometry car from MerMec for use on the Paris metro network, the supplier announced on May 2.

The car will be equipped with a conventional diesel power pack but it will also be able to draw traction power from the third rail where this is energised. MerMec says that most track recording vehicles have been diesel powered to give maximum operational flexibility, but concerns over emissions and noise have led RATP to choose a dual-mode variant.

MerMec says that the car’s ultrasonic flaw detection system will be able to operate at at up to 60 km/h, reducing the amount of time required for the vehicle to be in service on the network.
