BLA meaning in Regional ?

The Baltimore & Annapolis Railroad was an American railroad of central Maryland built in the 19th century. The railroad, the second to serve Annapolis, ran between Annapolis and Clifford along the north shore of the Severn River. From Clifford, just north of the present day Patapsco Light Rail Stop, it connected with the B&O's Curtis Bay branch so that trains could travel to Baltimore. In 1921, when it was called the Annapolis and Baltimore Short Line, it was purchased by the larger Washington, Baltimore and Annapolis Electric Railway (WB&A), and then emerged from the WB&A's 1935 bankruptcy and closure as the Baltimore & Annapolis Railroad. B&A electric passenger operation between the two cities continued until 1950, at which time the rail line became solely a freight carrier, operating buses for passenger service. Freight service to Annapolis continued until June 1968 when the Severn River Trestle was declared unsafe. In the 1980s the line was completely shut down. The right-of-way now serves as part of Baltimore's light rail system and as the Baltimore & Annapolis Trail.
