The photo you have marked as San Francisic is the Market Street Railway's Elkton shops. It was located at the corner of Geneva and San Jose Avenues until about 1976. It was built as a temporary facility after the 1906 earthquake and fire. Clearly shown in the photo was the monorail crane that ran around the shop. It had a very small cab where the operator sat. I believe it is still in existence. There was no AC power in Elkton until very late. Just to the right of the photo was a 550 to 250 volt DC motor generator to provide power for the machines. There were many machines still powered by 250 VDC when the shop closed. The shop was very complete with a machine shop, blacksmith shop, foundry, wood mill and motor shop. Many cars were built complete there. In later years all the cable cars were rebuilt here. When I spent time there the bays were filled with PCC cars. Best part of Elkton was it had a basement. Never know what you might find there.
The photo marked some where in the east in interesting. Fairly modern building and crane. Looks like a Boston PCC on the left. I do not recognize the other cars. I wounder if it is Brookville Locomotive Works.
