I thought it was the 2x6 that was the last. No?
You are correct as to the Monson Railroad running longer than the Bridgton. What Adam asked was a bit tricky in that he stated "above ground common carrier". As Monson was not a common carrier, Bridgton was the last (above ground).
The answer Adam was looking for was the Chicago Tunnel Company, which is the "below ground" last common carrier of two foot gage.
Old photo collectors may recall back in the 1970's, the late Bob Werner, Jr. began selling 5" X 7" black and white prints from his hobby shop in Plymouth, Massachusetts. Local narrow gage fans would visit the store each Friday and buy whatever new prints Bob had made up over the previous week. Bob told me that he "doled out" a half dozen or so each week, to build up foot traffic in his store.
Two fellow W.W. & F. Ry. Museum members that I know of, went each week to buy what eventually became around 200 prints.
Within that collection was one photo of a two foot gage electric freight motor. The machine was pictured at the Baldwin Locomotive Works in a builders photo pose. Presumably, a Chicago Tunnel Company motor, the tiny unit had the standard (full size) Baldwin builders plate.
I was fortunate to receive the entire photo collection from Channing H. Morse, Jr. before he passed away. The Morse collection has many of Linwood Moody's photos, though without the classic red backstamp of "Moody Railroad Photos - Union, Maine - Eda Charlene Heald, Agent"
(Sorry, Mike...more than you wanted to know! 🙂)
