Toy Train Layout?

Christmas is coming, which for many railfans means time to break out the train set and set it up under the tree. This shot looks a bit like that, but it’s actually the back of Cameron Beach Yard, where the ladder track (a series of switches connecting the various tracks in the shop building) is being replaced, part of Muni’s ongoing re-railing activities. The vintage streetcars aren’t much affected; they just back into the shop tracks from the other side. The switches serving the storage tracks under the canopy, at the other end of the yard, haven’t yet been replaced.
