The line ran from New Castle north to Stoneboro (later Mercer), and is now entirely abandoned.
[1] The New Castle Branch (and the Wolf Creek Branch, a short spur of it) was the only part of the Western New York and Pennsylvania Railway operated by the Pennsylvania Company as part of the Lines West of Pittsburgh rather than by the Pennsylvania Railroad as part of the Lines East of Pittsburgh.
The Pennsylvania Company also operated the trackage rights from Stoneboro to Oil City.
The BNY&P was reorganized as the Western New York and Pennsylvania Railroad in 1887, and again as the Western New York and Pennsylvania Railway in 1895.
[7] Passenger service was last operated over the branch on June 9, 1931,[8] and the line north of Houston Junction (near Mercer) was abandoned in 1938.
