The Northeast Corridor, running between Boston and Washington via New York City and Philadelphia, is one of the most significant railroad corridors in the country.

The line, which carries more than 2,200 trains every day, dates to the earliest days of railroading in America. Several railroads built the corridor at various times between 1830 and 1917.

One railroad instrumental in building the line that would eventually become the Northeast Corridor was the New Jersey Rail Road. The railroad was chartered to build a road between Jersey City and New Brunswick.
