The 米国 has a limited passenger 鉄道ネットワーク relative to its size, with アムトラック as the national インターシティ operator subsidized by the federal government. アムトラック サービス over 500 stations in 46 states, with the Northeast Corridor (NEC) being by far the busiest: the Acela Express 達する 240 km/h between Washington DC and ボストン, covering the DC-ニューヨーク leg in 2h45m and ニューヨーク-ボストン in 3h30m. Outside the NEC, most アムトラック trains operate at conventional speeds on freight-owned track where passenger trains are legally given lower priority, causing frequent delays. Long-distance アムトラック trains serve iconic cross-country routes: the California Zephyr (シカゴ to San Francisco, 51h), the Empire Builder (シカゴ to Seattle, 46h), the Southwest Chief (シカゴ to ロサンゼルス, 40h), and the Coast Starlight (Seattle to ロサンゼルス, 35h). These trains offer Superliner sleeping cars with roomettes and bedrooms, a dining car, and a sightseeing lounge. They are more tourism than 通勤-focused, and delays of several 時間 are common. Several states and regions have developed 通勤 rail networks independent of アムトラック: MBTA (ボストン), Metro-North/LIRR/NJ Transit (ニューヨーク area), SEPTA (Philadelphia), MARC/VRE (Washington DC), Metra (シカゴ), BART/Caltrain (San Francisco), and Metrolink (ロサンゼルス). The Brightline 民間事業者 運行 Florida services and is expanding. High-speed rail projects in California and the Northeast face persistent funding and regulatory challenges.
