At most times, the line operates from the Patapsco light rail station in southern Baltimore County with short turns at Jumper's Hole in Pasadena.

The bus route, one of the longest local routes operated by MTA, is the successor to the Baltimore and Annapolis Railroad interurban, and mainly operates along the parallel Ritchie Highway, serving Brooklyn Park, Glen Burnie, Pasadena, and Severna Park.

When the Central Light Rail Line opened in 1992 along part of the old interurban line, Route 14 was truncated to the Patapsco stop during Light Rail operating hours, with selected trips deviating to Bay Meadow Industrial Park.

The other operates to Jumper's Hole via a variation of this route to serve the Quarterfield Shopping Center, which is the location of a Wal-Mart Supercenter.
