One of my co-workers over the 4th of July weekend took a trip down the Allagash Waterway and visited the site of the locomotives of the former Eagle Lake & West Branch railroad. The Railroad was built in the late 1920s and operated for only a few years. It replaced a tramway which hauled logs from Eagle to Chamberlain lake. The railroad ran from Eagle to Umbazooksus lake. These structures were built to move lumber from the Allagash Waterway, which flowed north into Aroostook county (and into the St. John which drained into Canada) and instead moved the lumber south onto the Penobscot river (the West Branch of the Penobscot for the railroad, the East Branch for the tramway).
The Maine Forest Service burned down all the wooden structures on the Allagash in the 60s, including the shed that these locomotives were in. Over the years the engines started to tilt over as the ground under them settled. About 10 years ago a group of people started working to right the engines, hauling in all supplies (including 5-gallon buckets of ballast) by snowmobile in the winter. The Maine Forest Service is turning this area into a display, including plans to restore a small portion of the tramway.
The equipment was left in-situ, and over the years the forest has regrown around things.

The track is now a path.

Locomotive #1, a 2-8-0 from I think the New York Central.

Locomotive #2, I'm not sure where it was from. It had a wooden cab which burned in the fire.

So how does this tie in with the WW&F?
About a dozen years ago, when Fred Morse joined the museum, he told us about seeing rail lying on the side of a logging road up in the north Maine woods. He may have even seen it lying on the ground when he and his family were hunting in the woods as a child. The search started to find out who we needed to contact and if we could get the rail.
The ownership search ended up being an essentially dead-end, but the story doesn't end there. Sometime around 10 years ago, Harry Crooker (owner of Harry Crooker & Sons) was either approached by us or approached us with rail to donate. Turns out this rail was from the Eagle Lake and West Branch! Additionally he had one of the Plymouth locomotives that was also used on the line. We could not take it, I don't know what happened to it.
You don't need to use a canoe to reach these locations, you can drive a car to within one mile of it, and then hike in. I believe someone in our group led several people up to the locos several years ago.
