The Northern Central Railroad began operation in 1832 to serve the growing industries of Baltimore, York, and Harrisburg. During 140 years of operation, the railroad had 146 stops, 22 of which were in Maryland. In 1984, the railroad was converted into the NCR Trail under the supervision of the Maryland Department of Natural Resources. Over the past 20 years, the trail developed into a popular recreational destination with the help of volunteers and through the support of Dr. Torrey C. Brown, its strongest believer and advocate. In honor of Dr. Brown's overwhelming support, the trail was renamed the Torrey C. Brown Rail Trail in 2007. The railroad's past remains evident in many fixtures and markers along the trail. Railroad enthusiasts can visit the historic Monkton Train Station, now a park visitor center and railroad museum. From 1898 until 1959, it operated as a passenger and freight station. The station fell into disrepair in 1959, but in 1980 the DNR began renovations, ultimately restoring the station to its present status at the heart of the rail trail.
