Mercer and Somerset Railway

The railroad ran from Somerset Junction on the Belvidere Delaware Rail Road via Pennington and Hopewell to Millstone.

[5][6] The Mercer & Somerset Railway lost its battle with the Delaware and Bound Brook Railroad.

At the beginning, it was leased by the United New Jersey Railroad and Canal Company and operated by the Belvidere Delaware Rail Road.

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 National Railway won the battle, and the Delaware and Bound Brook Railroad formally opened on April 27, 1876.
