Maine Central

Maine Central ordered “two 3000 HP Diesel Freight Locomotives” on 20th November 1947, with for $645,300 each as their first diesel freight locomotives. The following month, until 671A&B and 672A&B, arrived; they were early Phase III “chicken wire” F3 units. Equipped with low roof fans, dynamic brakes and steam generators in all four units, they were used on the overnight Portland-Worcester run of the State of Maine and Portland-Bangor symbol freights, at that time numbering four in each direction.

The Class DF-3 was built with “chicken wire” grills and steam generators for possible use on passenger trains, but all Maine Central F3s spent most of their lives pulling freight trains on the mainline and Mountain Subdivision. Class DF-4 had the EMD F7-style grills and were sometimes called F5s. The F3s were traded in for EMD GP38s in 1966.

Green paint started in 1956, passenger service was just about gone so it’s believed that the steam generators would have been removed prior to receiving green paint.
