A tight fit. With her end-of-day servicing complete, Boothbay Railway Village's Henschel #6 gingerly backs into the museum's little engine shed, adjacent to the Thorndike Station. The 6 joins sister Henschel #7, which was parked in the back of this structure when the photo was taken. As I watched this operation, it occurred to me that the clearance between the top of the stack on this engine and the roof of the doorway was probably not more than an inch or two.
Incidentally, Boothbay Railway Village now has a 3rd engine which is operable, and this time, it's an American Baldwin industrial saddle-tanker. The little SD Warren #2 completed it's multi-year restoration just days before my visit. In fact, the ceremony to introduce her to the public took place just the day before this photo was taken. I was hoping to see her in steam this day, but alas, the museum only had one engineer who was trained on her, and he was not working this day. :(
