More comprehensive answer: Geography, population, pre-existing infrastructure, and rail ownership are the major reasons. Climate and history matter, too. Let's compare the US to the two major high-speed rail countries (Japan and France).

CLIMATEWIRE | The first U.S.-made high-speed bullet trains will start running as early as 2024 between Boston, New York and Washington, with the promise of cutting transportation emissions by attracting new rail passengers who now drive or fly.
Trenitalia's Paris to Milan route was first introduced in December 2021, serviced by Hitachi Rail's ETR1000. This super high speed train travels at 300km/h - with the ability to go400km/h if not limited by track regulations - making it the fastest train in Europe.
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.
The plan to build a high-speed train that will connect Las Vegas with Southern California took another important step this month. The massive transportation project by Brightline could begin as soon as this year, with an estimated completion plotted for around 2027.
In 2008 when voters approved the bond measure for the train, the cost to connect the 500-mile span would be around $33 billion. Today, the whole 500-mile system would cost a grand total of $128 billion. That price tag has left state officials scratching their heads to bridge that $100 billion funding gap.
The report concluded that although a high-speed rail system could have a place in Australia's transport future, it would require years of bipartisan political vision to realise (construction time was estimated at 10–20 years), and would most likely require significant financial investment from the government – up to 80 ...
Over 2,800 pairs of bullet trains numbered by G, D or C run daily connecting over 550 cities in China and covering 33 of the country's 34 provinces. Beijing-Shanghai high speed train link the two megacities 1,318 km (819 mi) away in just 4.5 hours.
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.
The Great Depression of the 1930s forced some railroad companies into bankruptcy, creating hundreds of miles of disowned and subsequently abandoned railway properties; other railroad companies found incentive to merge or reorganize, during which excess or redundant rights-of-way were abandoned.
California's plan is to build an electric train that will connect Los Angeles with the Central Valley and then San Francisco in two hours and 40 minutes. But 15 years later, there is not a single mile of track laid, and executives involved say there isn't enough money to finish the project.
According to the latest data, as of the first half of 2022, the total liabilities of China National Railway Group totaled 6 trillion yuan, and in the first half of 2022 alone, it has lost 80.4 billion yuan, with an average loss of 400 million yuan per day.
1: Shanghai Maglev - 460 kph/286 mph (China)The world's fastest public train is also unique – it's the only link in the world currently carrying passengers using magnetic levitation (Maglev) rather than conventional steel wheels on steel rails.
Along the current route of the Eurostar service, line speeds are 300 km/h (186 mph) except within the Channel Tunnel, where a reduced speed of 160 km/h (100 mph) applies for safety reasons.
