China plans its first undersea high-speed railway tunnel at 10 miles long
- Passage is part of a new £4.5 billion railway project in Zhejiang, eastern China
- Trains will travel at 155mph under the East Sea between Ningbo and Zhoushan
- Beijing is currently studying the feasibility of the plan, according to local media
China is planning to build its first undersea high-speed railway tunnel.
The underwater passage will be 16.2 kilometres (10 miles) long and support trains that operate at the speed of 250 kilometres per hour (155 miles per hour), according to a plan which is under evaluation by Beijing.
The underwater high-speed railway is part of a new 40 billion yuan (£4.5 billion) train line, the Yong-Zhou Railway. It is set to connect the cities of Ningbo and Zhoushan in Zhejiang province.

The undersea tunnel will link the Beilun District of Ningbo with the Jintang Island of Zhoushan
The tunnel will run under the East Sea and link the Beilun District of Ningbo with the Jintang Island of Zhoushan.
The Yong-Zhou Railway is set to be a rail-road project, which will facilitate high-speed trains as well as vehicles, according to Zhejiang News citing a statement from the Ningbo government.
The traffic link will be 77 kilometres (48 miles) long and have seven stations. Trains and cars will travel across the sea in two separate tunnels - both to be constructed.
The railway is expected to shorten the travel time between Ningbo and Zhoushan from around an hour and a half to just 30 minutes.
The report said experts were currently studying the feasibility of the construction plan. A recent discussion was held in Beijing and experts were positive about the project.

The news comes just a month after China opened the world's longest sea-crossing bridge, which runs 55 kilometres (34 miles) and includes a 6.7-kilometre (four-mile) undersea tunnel.
Earlier this month, Chinese workers finished building a tunnel under the Yellow Sea for subway trains and it reached as deep as 88 metres (288 feet). The passage is about 100 feet deeper than the Bosphorus rail tunnel in Istanbul, which is said to be the world's deepest underwater railway tunnel.
