up to 300 km/h, moving 23,000 passengers a day. The line was to have been extended over 210 km, with construction beginning that year and operations starting in the second half of 2017. On 6 November 2014, Mexico's president announced that the proposed bullet train was being postponed because there was only one bidder. Falling oil prices and the economic downturn was also believed to have played a role in the decision. In July 2018, Mexican President Andrés Manuel López Obrador revived the project, and in 2020 the Mexican government secured a 51.3 billion peso investment (US$2.3 billion) to fund the high speed rail project. As of 2022, 80 million pesos (US$3.93 million) have been allocated for initial feasibility studies, with the remaining funds planned through 2025. In 2021, Mexican rail officials began a US$2 million feasibility study for a rail connection between San Antonio (US) and Monterrey (Mexico); unlike previous US$20 billion proposals for the line to be built for 250 mph (400 km/h) operation, this US$7 billion proposal examines a 100 mph (160 km/h) route which would take 4 hours. Panama In 2019, China approached the Panamanian government with a feasibility plan for a 391 kilometer (243 mile) high speed line from Panama City to David, on the Costa Rican border. This would have been financed partially under China's Belt and Road Initiative. The project was dismissed by the Panamanian president Laurentino Cortizo in September 2019, who stated that taking on the project would be a debt overload. United States There are several high-speed rail services in the United States, notably the Acela Express, but all are limited to the Northeast Corridor. Amtrak uses the Acela Express as a high-speed service between Washington, D.C. and Boston via New York City and Philadelphia along the Northeast Corridor (NEC) in the Northeast United States. The tilting design allows the train to travel at higher speeds on the sharply curved NEC without disturbing passengers, by lowering lateral forces. The Northeast Regional goes along the same route, but with more stops. All other high-speed rail services share part of the route. There has been a resurgence of interest outside the Northeastern Corridor in recent decades, with many plans being examined for high-speed rail across the country: In 2002, the Texas High Speed Rail & Transportation Corporation (THSRTC), a grass roots organization dedicated to bringing high-speed rail to Texas, was established. In 2006,
