Rail transportation in the United States consists primarily of freight shipments, with a well integrated network of standard gauge private freight railroads extending into Canada and Mexico. Passenger service is mainly mass transit and commuter rail in major cities. Intercity passenge service, once a large and vital part of the nation's passenger transportation network, plays a limited role as compared to transportation patterns in many other countries.
