64, a trailer converted from a motor car.
(Per Every Hour on the Hour, CERA 130) this car had an interesting history.
It was built by Niles in 1910 as part of a nine-car order (wood, railroad roof). It burned in March 1923 and was rebuilt in the WBandA shops in May 1924 in a steel, arch-roof configuration.
In 1935, presumably after the WB&A's abandonment, it was sold to the Boston Iron and Metal Company. In 1944, the latter company sold it to the BandA for use as a trailer. In the 1924 rebuilding, it lost 5 inches of length, 1 inch of width, and 3 inches of height.
The Baltimore and Annapolis was the final hurrah for the WBandA, coming into being out of the bankruptcy of the WBandA in 1935. It was run by the BandO, and continued electric operations between Annapolis and Baltimore until 1950
