Other than a few Alco road switchers, the Maine Central's road power was largely EMD until GE sold them ten U18 "baby boats" in 1975. Later, the MEC ended up with two classes of secondhand U-boats. Fourteen U25B’s came from the Rock Island as part of that road’s liquidation, and Guilford shuffled power between its roads, resulting in fourteen D&H U23B’s landing on the MEC roster. Here an example of each of the secondhand classes, in GTI paint, stand in the D&H engine terminal in East Binghamton.
