How did China build high-speed rail?

China initially relied on high-speed technology imported from Europe and Japan to establish its network. Global rail engineering giants such as Bombardier, Alstom and Mitsubishi were understandably keen to co-operate, given the potential size of the new market and China's ambitious plans.

High-speed tunnel construction costs in China are about $US 10-15m/km, a fraction of that in other countries. Tunnel costs are heavily influenced by geology and labour costs and, in the case of China, the latter has certainly helped to keep costs down.

He said there are only a few examples of high-speed rail networks that turn a profit, due to a rare combination of passenger numbers and distance. For example, most of the companies that run Japan's Shinkansen or bullet train lines operate at a profit, as do some fast trains on France's state-owned SNCF network.

There are limits to running trains with tradition wheels and railway track. Wind resistance, infrastructure wear and traction motors all add to the difficulties in running ever faster trains. Power consumption increases disproportionately as speed rises. Most European high speed trains have a top speed of 300 km/h.

High-speed trains are European-standard high-speed inter-city trains, capable of typical ground speeds of 250 kph (or 155 mph). They currently run between Moscow, St. Petersburg, Helsinki, and Nizhny Novgorod. These trains are called Sapsan within Russia, or Alstom on the Helsinki – St.
