The third of the two footers was the Monson Railroad, also known as the “two by six” because it was only six miles long. The Monson Railroad was a slate hauler and ran from the quarry near Monson to Monson Junction. The guiding hand in the Monson was H. E. Morrill, Superintendent of the railroad. He retired in 1938 and the road did not last long after that, being abandoned in 1943. Fortunately for railfans everywhere, two of the Monson engines, #3 and #4, were saved from scrappers and now run in Portland and Phillips (Sandy River).
