CHINA: Trials are underway with an overhead electrification inspection, maintenance and repair vehicle capable of running at up to 160 km/h when travelling to worksites on high speed lines.

The multi-functional vehicle has been developed by CNR Beijing February 7 Railway Transportation Equipment Co, based on the Class 711 which is in service with DB Netz. It designed to be able to operate in tunnels, on steep gradients and in icy or snowy conditions, and has separate engines for high speed and low-speed operations. It carries seven technical staff, with a roof-mounted extendable platform to provide access to the overhead electrification equipment.

The manufacturer estimates that there is a potential market for 400 units in China.
