The Northern Central Railway (NCRY) was a Class I Railroad connecting Baltimore, Maryland with Sunbury, Pennsylvania, along the Susquehanna River. Completed in 1858, the line came under the control of the Pennsylvania Railroad (PRR) in 1861, when the PRR acquired a controlling interest in the Northern Central's stock to compete with the rival Baltimore and Ohio Railroad (B&O). For eleven decades the Northern Central operated as a subsidiary of the PRR until much of its Maryland trackage was washed out by Hurricane Agnes in 1972, after which most of its operations ceased as the Penn Central declined to repair sections. It is now a fallen flag railway, having come under the control of the later Penn Central, Conrail, and then broken apart and disestablished. The northern part in Pennsylvania is now the York County Heritage Rail Trail which connects to a similar hike/bike trail in Northern Maryland down to Baltimore, named the Torrey C. Brown Rail Trail. Trackage around Baltimore remains in rail service as well as most of the trackage in Pennsylvania which is operated by Norfolk Southern and the southernmost section in Pennsylvania is operated by the Northern Central heritage railway.
