I recently found this snapshot of lower Georgia Avenue dated December 12, 1943. According to the writing on the back of it, it shows Capital Tranist car #1334 at the Georgia Avenue plow pit. Back when Washington had a citywide streetcar system, the areas outside of the original city used overhead wires. When cars reached the point where they switched to overhead operation, they stopped over a plow pit like the one shown on Georgia Avenue where the conduit plows were detached and the trolley poles raised. The reverse operation occurred on inbound runs.
The photo above shows a northbound streetcar, so it is in the early stages of switching to overhead operation (the pole has not been raised yet).
It’s also interesting to see the Wonder Bread factory in the background, which was originally Corby Bakery. The building today is known as Wonder Plaza.
