The United New Jersey Railroad and Canal Company traversed the region in 1830, eventually becoming the Pennsylvania Railroad (PRR). NJT's Northeast Corridor Line and the North Jersey Coast were once part of the PRR, as was Amtrak which serves the commuter hub at Metropark, New Brunswick, and the Trenton Transit Center. The Central Railroad of New Jersey once connected Jersey City (with connecting ferries to Manhattan) and many Central Jersey towns. Much of that system is now included in New Jersey Transit rail operations to the Raritan Valley. New Brunswick is known as the Hub City, and at one time was a regional transportation hub for streetcars which converged in the city. The Monmouth Ocean Middlesex Line has been proposed for the region.
