The Acela Express (colloquially abbreviated to Acela) is Amtrak's flagship service along the Northeast Corridor (NEC) in the Northeastern United States between Washington, D.C. and Boston via 14 intermediate stops, including Baltimore, Philadelphia, and New York City. The route contains segments of high-speed rail, and Acela Expresstrains are the fastest trainsets in the Americas; they attain 150 miles per hour (240 km/h) on 33.9 miles (54.6 km) of the route Acela operates along routes that are used by freight and slower regional passenger traffic, and only reaches the maximum allowed speed of the tracks along some sections, with the fastest peak speed along segments between Mansfield, Massachusetts and Richmond, Rhode Island. Acela trains use tilting technology, which helps control lateral centripetal forces, allowing the train to travel at higher speeds on the sharply curved NEC without disturbing passengers.[8] The high-speed operation occurs mostly along the 226-mile (364 km) route from Pennsylvania Station in New York City to Union Station in Washington, D.C., with a fastest scheduled time of 2 hours and 45 minutes and an average speed of 82.2 mph (132 km/h), including time spent at intermediate stops.Over this route, Acela and the Northeast Regional service captured a 75% share of air/train commuters between New York and Washington in 2011, up from 37% in 2000. The Acela's speed is limited by traffic and infrastructure on the route's northern half. On the 231-mile (372 km) section from Boston's South Station to New York's Penn Station, the fastest scheduled time is 3 hours and 30 minutes, or an average speed of 66 mph (106 km/h).Along this section, Acela has still captured a 54% share of the combined train and air market.The entire 457-mile (735 km) route from Boston to Washington takes between 6 hours, 38 minutes and 6 hours, 50 minutes,at an average of around 70.3 mph (113 km/h). Service type: Inter-city, high speedtilting train
It is very clear you just copied this from Wikipedia. While I agree it would be great to have this train, it wouldn't be used to its full potential as the NEC route in TSW only reaches 100 mph for less than a mile and is less than 30 miles long in length.
I think the if the Acela Express is added then NEC New York must be expanded to Philadelphia 30 St Station.
