New Castle Subdivision

The New Castle Subdivision is a railroad line owned and operated by CSX Transportation in the U.S. states of Pennsylvania ond Ohio. The line runs from New Castle, Pennsylvania west to Greenwich, Ohio along a former Baltimore and Ohio Railroad line.

At its east end, near Mahoningtown, the New Castle Subdivision becomes the New Castle Terminal Subdivision. Its west end is at the Willard Terminal Subdivision just east of the Greenwich Subdivision junction at Greenwich. Along the way it junctions with the Newton Falls Subdivision at Newton Falls, Ohio and the CL&W Subdivision at Sterling, Ohio.

The Pittsburgh, Cleveland and Toledo Railroad opened the modern New Castle Subdivision from New Castle to Youngstown, Ohio and a line continuing west to Valley Junction (near Akron, Ohio) in 1884; most of the current line west of Youngstown was built later (part of the old alignment is now the Newton Falls Subdivision). The rest of the line, from Akron west, opened in the 1890s as the Akron and Chicago Junction Railroad. The line became part of the B&O and CSX through leases and mergers.
