A model 15 T tram, built by A Škoda, makes it way through the small tunnel underneath a building on Letenská street in Lesser Town. I didn't notice when I took this photograph, but the two tracks actually don't join together. If you look closely, you can see that they stay separate, so that the two tracks can fit through the narrow tunnel.
