The Northern Central Railway (NCR), completed to Sunbury in 1858, was a
Class 1 railroad that connected Baltimore City, Maryland, to Sunbury,
Pennsylvania. In 1861, the Pennsylvania Railroad acquired controlling
interest in the railway. It became such a vital transportation link
during the Civil War that it had to be guarded constantly by Union
forces. In June 1972, Tropical Storm Agnes heavily damaged much of the
NCR right-of-way in Pennsylvania and all but destroyed the right-of-way
in Maryland. Then under control of Penn Central, it was decided to
repair only the tracks in Pennsylvania and abandon the Maryland section
from Cockeysville to the Maryland state line. The majority of the route
in Maryland is now the Torrey C. Brown Rail Trail in Baltimore County,
and the portion in York County, Pennsylvania, is now the Heritage Rail
Trail. The extreme southern end of the line from Baltimore City to
Cockeysville in Maryland is now used by MTA-Baltimore Light Rail system.
