SHENZHEN Metro (SMZC) has awarded Vossloh a contract for emission-free grinding machines, which are claimed to be the first of their kind in the world.
The contract is initially for three high-speed grinding trains (HSG-city) for use on the city’s 411km metro network.
They will operate by coupling to an electric traction unit. The HSG-city draws its power from the conductor rail, meaning it can operate emission-free.
Vossloh says its unique grinding process enables means maintenance machines can operate at speeds of up to 80km/h on the mainline and 60km/h on metros. This allows maintenance work to be conducted without having to stop commercial operations, making timetable adjustments or closing lines.
Vossloh says China is currently the company’s most important market for innovative rail maintenance products.
