1. Cost: Building a high-speed rail network requires significant investment in infrastructure, including tracks, stations, and maintenance facilities. The cost of constructing such a network in a large and geographically diverse country like the United States can be prohibitive.
What is the longest high-speed rail line in the world?
Beijing–Guangzhou high-speed railwayNotable HSR lines in China include the Beijing–Guangzhou high-speed railway which at 2,298 km (1,428 mi) is the world's longest HSR line in operation, and the Beijing–Shanghai high-speed railway with the world's fastest operating conventional train services.
Why the US don’t have high speed trains?
The interstate highway system cost $129 billion — roughly $290 billion in current dollars — and took 35 years to complete, running from 1957 to 1992. The $1.2 trillion infrastructure bill enacted in 2021 has $102 billion for rail, but none of the money is set aside for high-speed rail.
