Somewhere, I don't remember if it came home with us or if is on display at Sheepscot, there is a pair of joint bars I found with one bolt and a very short piece of rail between them. It was found on the outside of the curve where Albees crossing is now. We surmised it was a repair joint. When the rails were replaced with better ones (nothing new you know), the joint bar was cast aside, missed by the scrappers.
There has also been whole rails found. One was located by where the siding was at the Top of the Mountain. Less than 10 feet from the track, missed by the scrappers, or left intentionally?
