CRRC Changchun Railway Vehicle Company, the makers of the trains, have also revealed details about the facilities which will be available on board.

They confirmed the trains, which have been specifically designed for use at the Winter Olympics, would have an athlete drug testing area.

The carriages will also be fully equipped with wi-fi and would include television screens showing live coverage of the action from the Games.

A dedicated media carriage will be installed on the trains to allow journalists to work while making the 194 kilometres journey between the two competition zones.

It is claimed it will reduce journey times from around three hours to one hour.

The cost of the network is thought to be around the ¥58.41 billion (£5.98 billion/$9.21 billion/€8.39 billion) mark and construction is set to be completed in 2019.

The Chinese capital, which also hosted the 2008 Summer Olympics and Paralympics, will be the home of the ice sports at the Games and will play host to ice hockey, curling and skating.

The majority of skiing events at the Games will be held in Zhangjiakou, located to the north-west of Beijing.

A 53.2km extension to the Beijing-Zhangjiakou high-speed railway network is also under construction to include Hebei's Chongli District, the location for freestyle skiing and biathlon.

The branch to Chongli will add around 25 minutes to the journey.

The extension is also due to be finished in 2019.
