Subway Boston

The Boston Subway is the first underground rapid transit system in America and is now expanded to Malden in the north, Braintree in the south and Newton in the west with a total length of 65.5 miles. Boston’s suburban commuter rail has a length of more than 200 miles with Worcester in the west and Providence in the south. Because of the compact urban layout and the numerous students, the number of the walkers reaches 13% and is higher than other cities at the same level.
