Acela Express (Paperback)

Acela Express is Amtrak's rail service that uses high-speed tilting trains. Acela operates along the Northeast Corridor in the Northeast United States between Washington, D.C., and Boston via Baltimore, Philadelphia, and New York. The tilting design allows the train to travel at higher speeds on the sharply curved NEC without disturbing passengers, by lowering lateral centrifugal forces, based on the concept of banked turns.Acela Express trains are the only true high-speed trainsets in the United States; the highest speed they attain is 150 mph (240 km/h), though they average less than half of that. Acela has become fairly popular with business travelers and by some reckoning has captured over half of the market share of air or train travelers between Washington and New York.In fiscal year 2006, a total of 2,668,174 passengers rode Acela, an 8.8% year-over-year increase.and in 2008 Acela carried 3.399 million passengers between New York and Boston.
