This began as a place to keep my notes for some modeling projects. I hope others find them useful; comments, corrections and contributions are welcome. At the moment, this is all I have on the Maine Central; more general information can be found in my New England Railroad History and Modeling page.
The MEC's steam roster was mostly purchased new, but a number of engines were purchased second-hand from the B&M over the years - several class S-1 2-10-2s and one H-2 0-8-0. Additionally, a number of B&M G-10 and G-11 0-6-0s and two more H-2 0-8-0s were purchased by Portland Terminal. See my B&M Steam Locomotives page for more information.
During the era of joint management, power was fairly freely pooled between the two railroads. MEC freight steamers usually only ran to Worcester, but passenger power ranged somewhat further. MEC S-class 2-8-2s were the heaviest freight engines permitted on the B&M's line from Woodsville to Berlin, and saw occasional service there until the B&M's 2-10-2s were re-sprung to allow them to take over.
Maine Central Steam Locomotives by E. B. Robertson has a complete post-1923 roster and a mix of diagrams and B&W photographs. This is a privately printed paperback book that has gone through a number of editions since it first appeared in 1979. An all-time locomotive roster of MEC and predecessors appeared in the Railway & Locomotive Historical Society publication Railroad History No. 152 Spring 1985. As far as I know, no MEC steam ran after 1954, but some engines were not scrapped until considerably later.
MEC USRA Mikados 621 - 626 were built by Alco at Schenectady in 1919. Their tender capacity was 16 tons of coal and 10,000 gallons of water. They were included in the S class with MEC-designed 2-8-2s built before and after them (601 - 620, 627 - 632), although the USRA engines were differently equipped and a bit bigger. I haven't seen any photos in "as delivered" condition. The best reference I've seen to date is an article in the May 1999 Railroad Model Craftsman; in it Robert Bennet explains how he detailed an HO scale Bowser cast metal kit as MEC 626.
