Generally, a rough estimate for a high-speed railway line is around 30,000 to 60,000 tons of steel per km.

Per mile, the New York project cost $2.6 billion, which is high even by U.S. standards. For example, the Purple Line in Los Angeles cost $800 million per mile.
High-speed rail lines are proposed for California, Nevada, Texas, Georgia and the Pacific Northwest, and already under construction in California's Central Valley.
It Takes Decades to Plan and BuildHowever, because of cost overruns and the pandemic, the authority now projects completion no earlier than 2033, nearly 40 years after planning began. Not all high-?speed rail lines may take this long, but two decades seems a likely minimum.
Heavy metals are the main types of environmental footprints in bridges, stations, and electric systems. Water pollutants are the main environmental impacts for rail and EMU systems, and the emissions of air pollutants are significant in subgrades.
High-speed train revolutionChina has built around 26,000 miles (42,000 kilometers) of dedicated high-speed railways since 2008 and plans to top 43,000 miles (70,000 kilometers) by 2035. Meanwhile, the United States has just 375 route-miles of track cleared for operation at more than 100 mph.
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.
Inflation and higher construction costs have contributed to the high price tag. The project has spent $9.8 billion so far, according to Brian Kelly, CEO of the California High-Speed Rail Authority. We knew we've had a funding gap ever since the project started, Kelly said.
HSR is surprisingly fast and can provide high capacity with low operating costs, yet its high infrastructure costs and frequent budget overruns outweigh its advantages. Air travel remains more time-efficient for many US trips and requires far less infrastructure.
According to a study on HSR in France and China by the International Union of Railways, “the carbon footprint of HSR can be up to 14 times less carbon intensive than car travel and up to 15 times less than aviation travel, even when measured over the full life cycles of planning, construction and operation of the ...
The cost per mile of the planned 520-mile California high-speed rail system, assuming it could actually be built for the current estimate of $80 billion, is $154 million per mile. And Amtrak's own estimates for replacing its existing Northeast Corridor with true high-speed rail work out to over $500 million per mile.
Amtrak's Acela, which reaches 150 mph (240 km/h) over 49.9 mi (80.3 km) of track and Brightline, which runs at 125 mph (201 km/h) in a dedicated ROW between Orlando and Cocoa, are the US's only high-speed rail services.
Wider Risks to the Chinese EconomyIn 2020, China Railway's final profit and loss statement recorded losses of ¥55 billion CNY (approx. ¥1.1 trillion JPY/ $7.9 billion USD), while in 2021, it was in the red by ¥49.8 billion CNY (approx. ¥1 trillion JPY/ $7.2 billion USD).
Cumulatively, the top 10 railway companies in the world generated revenue of $237,432 million, with average revenue growth of 0.57%, the highest revenue was generated by Deutsche Bahn AG ($55,666 million), followed by SNCF Group ($41,094 million) and Indian Railways ($27,326 million), while Canadian National Railway Co ...
