Dresden has a long history as a center for transportation. The first horse-drawn streetcars started transporting passenger in 1872, but electric streetcars were already operating in 1893. The city, along with the transportation network, was pretty much destroyed during World War II, but today the tram network is alive and well with twelve routes and 200 km of track. Here's a view of Dresden before it was bombed beyond recognition.
Here's an image of the square in 1950 taken by Roger Rössing and Renate Rössing. Note that two of the streetlights remain.
