Herbert Run

Deep Run is an 11.9-mile-long (19.2 km) tributary of the Patapsco River in central Maryland in the United States. The main stem arises in the vicinity of Ellicott City, starting in the Montgomery Meadows housing development, and the lower course forms part of the border between Howard and Anne Arundel Counties. It passes underneath Route 100 twice, Interstate 95 once, and Route 1 once as well. Archeological digs in 1929 discovered arrowheads, spearpoints, axes, and gorgets along the Disney farm. The banks of the Deep Run were a regular hiding place for slaves travelling north with the assistance of Harriet Tubman. The area was rezoned by the Howard County Department of Planning and Zoning to be unpreserved for historical status and is now occupied by commercial buildings along Hi Tech drive and Oxford Square development.

St. Denis station is a passenger rail station on the MARC Camden Line in the Maryland town of the same name. While the small station is the line's closest station to its terminus at Camden Yards in Baltimore, it has low ridership. St. Denis station contains two platforms and three tracks. The southbound platform, located on the corner of Arlington and Maple Avenues, has a shelter that is made of plexiglas and aluminum. MARC gives this platform as the official address of the station. The northbound platform contains a wooden shelter on an embankment at the end of East Street with the name of the station on the back of it. The station also contains two at-grade wooden pedestrian crossings, one which spans the entire right-of-way from Arlington Avenue to East Street, and the other which only runs from the southbound platform on Maple Avenue to the middle tracks. East of St. Denis, the Camden Line crosses over the MARC Penn Line south of the Halethorpe MARC station. The station itself, is an excellent spot for railfanning due to its proximity to Baltimore and its location at a point that sees Capital Subdivision, Baltimore Terminal Subdivision, and Old Main Line Subdivision freight traffic. A junction leading to the B&O Railroad Museum also exists between here and the terminus at Camden Yards.
