This all-volunteer-run museum recalls a mode of transportation long forgotten by most Baltimoreans. Yet here they are, 18 of the actual cars that once carried passengers all over the city and into the surrounding suburbs—from the newest car, the 7407 that was built in 1944 to a turn-of-the-20th century open car that may remind visitors of San Francisco's Cable Cars (it was used as a cable car trailer in the 1890s and later was electrified). Seeing the old streetcars is nice; riding on them is even better. Come early and take a ride on up to three different streetcars. The motormen get these babies going to speeds of 12 to 15 miles an hour as they take the 20-minute trip out past an old Maryland-and-Pennsylvania Railroad roundhouse and back. Conductors reminisce about the many eras of the streetcar as they go. The grease monkeys among us may request a tour of the car house, though dark and dingy, where all the magic of maintenance and restoration goes on. Opening hours are limited but group tours on other days can be arranged.
