I'm looking for a DETAILED map of this system. Any ideas? A few years ago a resident of Hampton NH called a friend of mine (he's a welder too) he had been digging in his yard, landscaping, and uncovered about 100 feet of rail, not a track, but individual rails, and what appears to be a flange guide, and did he want it? (you're a welder, its steel, you could use it, just get it out of my yard) We know the line ran along this street, and wonder what else was there. We think there was a passing siding but can't find a system map with any detail.
