The Bay Ridge and Annapolis Railroad was a 4.5-mile long short line railroad in central Maryland. It ran 4.5 miles from a junction with the Annapolis, Washington and Baltimore Railroad to the resort town of Bay Ridge, Maryland. It mainly provided transportation between Annapolis and the resort, but also connected with a car ferry and steamer service to the Eastern Shore. A small connection was eventually made to the Baltimore and Annapolis Short Line. Shortly after opening it fell under the control of the Baltimore and Ohio Railroad. It was never able to make money so it was shut down in 1904 and the tracks were removed in 1918. Very little sign of it remains today.

The Bay Ridge and Annapolis Railroad was incorporated by the Bay Ridge Company in March 1886. The Bay Ridge Company rebuilt the beach resort on the Chesapeake Bay in 1885. The hotel was doubled in size, the boardwalk expanded, and beach cottages were constructed. The company even opened a zoological exhibit with lions, tigers and bears.

The railroad began operation on July 10, 1886 and for the next 17 years, thousands of people used it to visit the "Queen Resort of the Chesapeake." The start up costs, however, were enormous, and in September 1886, the Bay Ridge Company issued $300,000 worth of bonds. Robert Gerrett, President of the Baltimore and Ohio Railroad, bought $150,000 worth of the bonds giving the B&O a controlling interest in the Bay Ridge Company and the Annapolis and Bay Ridge Railroad.

At a point prior to 1890, a small connection was made from Chesapeake Junction to the Baltimore and Annapolis Short Line near West Annapolis.

For 13 months in 1890-91 the BR&A connected to a carferry and steamer service run by the Baltimore and Eastern Shore Railroad. That service ended in October 1891 and was replaced by a steamer-only operation out of Baltimore.

The railroad was never profitable and in 1904 it ceased operations. In 1918, with steel at a premium due to World War I, the tracks were removed.

Even though the railroad tracks have long been removed, many portions of the line's right of way are still visible.  The tracks ran alongside of Amos Garrett Blvd from West Street to the end of Amos Garrett at the water. From the end of Amos Garrett was a bridge that crossed over Spa Creek into where Truxtun Park is today. If you are familiar with the park, you may have seen the point that looks over Spa Creek (there is a memorial bench on this point). Near that spot is where the tracks came across. There is still an old 'Cable Crossing' sign where the bridge was.  The tracks then came through Truxton park and ran towards Spa Cove Apartments. In the park is an area frequently called 'The Horseshoe'. This is the gravel U-shaped lot where visitors and boaters frequently park. The tracks where the line of trees that seperates the Horseshoe and the large pavillions closest to the boat ramp. The tracks then crossed where Primrose Road is now, crossing about where the small traffic circle is for the apartments towards the back.

After crossing Primrose Road, the tracks continue on to a small street called Elliott Road. The tracks ran alongside of Elliott Road, then crossed over where Tyler Ave is today. The tracks then ran along where Conley Drive is today. If you look at the homes along the North Eastern side of the roadway, the tracks would have been at the rear of the back yards of these homes. The tracks then continued towards Bay Ridge Ave in the area of Bank Street and Cedar Ridge Court. The tracks would have crossed Bay Ridge Ave not from where the SPCA is located. The tracks then continued out towards the Bay Ridge area and ending near Tolly Point towards the very end of Bay Ridge.
