How is China able to build high-speed rail so fast?

By 2021, improved precision and the ability to work 24-7 had allowed automated rail construction to install up to 2km of track per day. Soon, robots had expanded their abilities beyond laying track. Welding, painting and inspection tasks could now be performed by robots.

How is high-speed rail built?

How Does the Rest of the World Build High-Speed Rail? Most countries use the Integrated Network Approach–gradually adding new segments of high-speed line to their existing network while upgrading connecting “shared-use” lines (which can be used by intercity, commuter, and freight trains) and local transit systems.

Who builds high-speed rail in China?

China's HSR accounts for two-thirds of the world's total high-speed railway networks. Almost all HSR trains, track and service are owned and operated by the China Railway Corporation under the brand China Railway High-speed (CRH).

How did China build high-speed rail?

How much does the China train system cost?

China's high speed rail with a maximum speed of 350 km/h has a typical infrastructure unit cost of about US$ 17-21m per km, with a high ratio of viaducts and tunnels, as compared with US$25-39 m per km in Europe and as high as US$ 56m per km currently estimated in California.

Why can’t we build high-speed rail?

Tracks: None of the nation's rail lines are built for trains to run 200 mph. Amtrak's Northeast Corridor — the busiest intercity U.S. passenger route by a wide margin — is filled with sharp curves, bottlenecks, decaying tunnels, bridges and overhead power lines that slow down trains.

Is high-speed rail profitable?

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.

Will the US ever build high-speed rail?

California's project, which is taking longer and costing more to build than envisioned when state voters approved a $10 billion bond to finance it in 2008, is the country's most ambitious but won't open until the 2030s at the earliest. Brightline thinks it can build its 218-mile route in four years.
