This door was actually on the side of a long building. I sensed that it had been there a good many years. Perhaps my imagination ran away with me, but I pictured it as the entrance to a speakeasy or something secretive (maybe illegal?). Nah, probably not. Judging from the weeds, it hasn't seen a lot of activity in recent months.
The engine is now leading the train back to the depot. There was one stop (at the water tower) on the way back and then we had the opportunity to go through both the caboose and engine. That was an interesting addition to our trip.
