Intelligent drive solutions provider Voith Turbo is set to provide two turbo transmissions each for 26 BR 711 CN high-speed overhead wire inspection vehicles ordered by China Railway Corporation (CRC).

BR 711 CN is currently entering production in China. These vehicles will be produced in cooperation with two European manufacturers.

China has granted a license for German rail maker Gleisbaumechanik Brandenburg’s (GBM) prototype. The company will be partnered with a Chinese manufacturer for additional support.

The Chinese Ministry of Railways, which licensed the prototype, has ordered a special rail maintenance vehicle that can carry out overhead wire inspection services and repairs efficiently during the relatively short maintenance windows. About 85 vehicles, equipped with a total of 170 turbo transmissions will be entering service in China in the near future.

"With a tested maximum speed of 176km per hour, it is currently the world’s fastest special rail vehicle."

With a tested maximum speed of 176km per hour, it is currently the world’s fastest special rail vehicle. Two diesel engines with capacity of 588kw each will ensure maximum drive power in the service railcar measuring 24.64m in length and weighing 84 tons.

The vehicle body will feature a workshop and a video station where the overhead wires can be monitored by pantographs and cameras. Its roof is equipped with two freely-mobile work platforms.

Voith said that a prototype with powerful T 312 turbo transmission was built based on type BR 711 fitted with a T 311 turbo transmission, which has been in operation in Germany since 2000.
