Mercer and Somerset Railway

The Mercer and Somerset Railway depicted on an 1876 New Jersey railroad map

The Mercer and Somerset Railway was a short-lived line of the Pennsylvania Railroad in western New Jersey, built to delay completion of the Delaware and Bound Brook Railroad, part of the National Railway line (later owned by the Philadelphia and Reading Railway) from Philadelphia, Pennsylvania to New York City.

The railroad ran from Somerset Junction on the Belvidere Delaware Rail Road via Pennington and Hopewell to Millstone, with a connection to the Millstone and New Brunswick Railroad for a through route to New Brunswick. Hopewell was the site of a frog war with the National Railway.

A plan existed at one time to extend the Philadelphia, Newtown and New York Railroad, another railroad being built to block the National Railway, to cross the Delaware River and connect with the M&S.

History

The railroad was chartered on March 17, 1870 by the United New Jersey Railroad and Canal Companies for the sole purpose of tying up the construction of the National Railway. [1] In 1873, the M&S had plans to straighten out the line as part of a new through railroad operated by the PRR. No straightening was done, but it did become PRR-operated. The railroad was formally opened on February 6, 1874, with an excursion train from Millstone to Trenton. At the beginning, it was leased by the United New Jersey Railroad and Canal Company and operated by the Belvidere Delaware Rail Road. By mid-1875, the railroad was being operated by the PRR as their Mercer and Somerset Branch, part of a through route from New York.

The M&S served as one of several legal challenges to the National Railway line from Philadelphia to New York. Others were the Philadelphia, Newtown and New York Railroad in Pennsylvania and a fight over whether they had the right to cross the Delaware River. The New Jersey-side one resulted in a frog war at Hopewell in early 1876. The National Railway won the battle, and the Delaware and Bound Brook Railroad formally opened on April 27, 1876.

The M&S was sold under bankruptcy to the Pennsylvania Railroad on November 28, 1879. It was soon dismantled, since it no longer served its purpose to block the National Railway. The abandoned grade of the west end of the line became Jacobs Creek Road.
