Green Tracks for Maryland’s Light Rail

The Maryland Transit Administration is testing a “Green Track” concept, establishing vegetation between and adjacent to light rail tracks.  Among the positive outcomes is a reduction in polluted stormwater running into local streams.

The question is: will the turf grass and/or sedums planted between the tracks survive in the railway environment and become established well enough to present a dense and attractive growth in Maryland?  If so, green tracks are to be considered for incorporation into portions of the Red Line, a 14-mile light rail transit line proposed in Baltimore City. Additionally, the Green Track concept is being considered for portions of the Purple Line, a 16-mile light rail project in Prince George’s and Montgomery Counties.

Green tracks are not uncommon in Europe, most notably in France and Germany. The benefits are many.  Some stormwater that would otherwise run off will be captured by the vegetation and soil. The temperature in the immediate area will be moderated, being a little cooler in the summer, reducing the urban heat island effect.  And, the noise from the trains will be dampened. Regular monitoring of Maryland’s Green Tracks test areas is currently underway.

Interested in seeing the green track test segments in person?

In mid-town Baltimore go to the Cultural Center Light Rail Station which is near the intersection of North Howard and West Preston Streets. There are two test areas here.

There is another test area in the suburbs near the Ferndale Light Rail Station in Anne Arundel County.  The test area is located between South Broadview Boulevard and Baltimore Annapolis Boulevard south of the station and the firehouse.
