The New York Branch or the Bound Brook Route was a railway line in Pennsylvania and New Jersey.

It formed part of the Reading's route from Philadelphia to New York City, used by the famed Crusader.

The North Pennsylvania Railroad portion began at Jenkintown, where it split from the Bethlehem Branch.

[2] The North Pennsylvania extended its line north from Jenkintown to Yardley, on the Delaware River, while the Delaware and Bound Brook constructed a new line from West Trenton to Bound Brook, New Jersey, where it joined the Central Railroad of New Jersey.

[4] The Baltimore and Ohio Railroad, involved in perennial disputes with the PRR, re-routed its passenger trains over the branch on October 1, 1880.
