Currently the only high-speed train in the United States, Acela runs from Washington, D.C., to Boston via Baltimore, Philadelphia and New York. It is the only part of Amtrak's network that actually makes money instead of losing it, and has been gobbling market share from commercial airlines. According to a recent New York Times story, 75% of travelers between New York and Washington now go by train; before Acela's arrival in 2000, only about one-third of travelers between those cities chose Amtrak.

Business travelers prefer Acela to flying because the train has power outlets, Wi-Fi and cellphone access, making it easy to work during the trip. They also don't face the security hassles of airports nor the long ground travel and waiting times that can erase the speed advantage of airplanes.
