China plans a 13,000 km rail line to US passing through a tunnel underneath the Pacific Ocean

“Right now we're already in discussions. Russia has already been thinking about this for many years,” Wang said.  

The project - nicknamed the ‘China-Russia plus America line' - would run for 13,000km, about 3,000km further than the Trans-Siberian Railway.

The entire trip would take two days, with the train travelling at an average of 350kmh.

Meanwhile, the official said the construction of ambitious Trans-Asian Railway Network connecting China with Myanmar, Laos, Vietnam, Cambodia, Thailand, Malaysia and Singapore is set to commence next month.
