It is located south of Elkridge, north of Savage, and close to Baltimore-Washington International Airport (BWI).

Dorsey is perhaps listed as a former postal stop that operated from December 1881 on the B&O railroad[improper synthesis?]

and is now a MARC commuter rail system stop, which carries commuters into downtown Baltimore and Washington, D.C.[1][2] Dorsey is a stop on MARC's Camden line and contains a large parking lot off Maryland State Highway 100.

[3][4] Dorsey station mainly serves commuters from Elkridge and Ellicott City, as well as the northern parts of Columbia.

Howard Transit buses connect the business park to the Dorsey MARC station.
