Easton and Amboy Railroad

The line was built to connect the Lehigh Valley Railroad coal hauling operations in Pennsylvania with the Port of New York and New Jersey to serve consumer markets in New York metropolitan area.

Until it was built, the terminus of the LVRR had been at Phillipsburg, New Jersey on the Delaware River opposite Easton, Pennsylvania.

[3] For three years, engineering and financial difficulties delayed the crucial tunnel through the Musconetcong Mountains at Pattenburg.

The Lehigh Valley Railroad then stepped in, purchasing the E&A and completing the line to Easton in 1875.

That connection was discontinued in 1891 after the LVRR established its own route to Jersey City from South Plainfield.
