The proposed line beginning from China's north east could go through Russia's eastern Siberia, the Bering Strait, Alaska, Canada and then reach the contiguous US, Wang Mengshu, a tunnel and railway expert at the Chinese Academy of Engineering, told the Chinese official media.
Once the line is put to use, bullet trains can run at 350 km per hour, enabling passengers to travel from northeastern China to the US in less than two days, he said, adding that Russia, which is heavily dependent on rail transport like China, is also progressively advocating the idea. Crossing the Bering Strait in between Russia and Alaska would require about 200km of undersea tunnel, the Beijing Times newspaper reported, citing Wang.
"Right now were 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.
The plan will begin with the construction of a 30-km long tunnel, stated to be the longest in Asia connecting China with Myanmar.
The engineering difficulties equivalent to those found in the construction of rail lines on the permafrost in Tibet, Wang said. China has already built a rail network up to Xigaze close to Arunachal Pradesh border.
China has completed 11028 km of high speed train network and another 12000 km tracks under construction.
Chinese officials in 2010 spoke of China's wish building a high speed train network connecting India and Pakistan.
