Here’s another cool old streetcar video. This is the The Washington & Great Falls Electric Railway line (“Cabin John Trolley”) from Georgetown. Disclaimer: the music is horribly cheesy, so you might want to mute it.

Here’s a little about it from Wikipedia:

Incorporated in 1892 and opened in 1895, The Washington & Great Falls Electric Railway began in Georgetown at 36th and Prospect Streets and ran in a private right-of-way along the lands of the Washington Aqueduct to Glen Echo and from there along the old tracks of the Glen Echo Railroad to Cabin John. Because the railroad never reached Great Falls, but instead terminated at Cabin John, it was often referred to as the “Cabin John Trolley”. It was acquired in 1902 by the Washington Railway and Electric Company. The railway was dismantled in the 1960s, but the former roadbed is still discernible in The Palisades and in Montgomery County, Maryland
