PROTOTYPE SPECIFIC INFORMATION
The EMD MP15 is a light road switcher that was built between 1974 and 1980. It came in two designs, the MP15DC and the MP15AC. It was billed as replacement for the EMD SW1500.
The MP15DC’s standard Blomberg B trucks were capable of transition and road speeds up to 60 mph (97 km/h), allowing use on road freights. Soon there was a demand for a model with an advanced AC drive system. The MP15AC replaced the MP15DC’s DC generator with an alternator producing AC power which is converted to DC for the traction motors with a silicon rectifier. The MP15AC is 1.5 ft (457 mm) longer than an MP15DC, the extra space being needed for the rectifier equipment. The alternator-rectifier combination is more reliable than a generator, and this equipment became the standard for new diesel-electric locomotive designs.
The MP15AC is easily distinguished from the DC models. Instead of the front-mounted radiator intake and belt-driven fan used on all previous EMD switchers, these have intakes on the lower forward nose sides and electric fans. Side intakes allowed the unit to take in cooler air, and the electric fans improved a serious reliability issue found in its earlier DC sisters.
In the early 1970s railroads were starting to convert to AC power, the six largest buyers, Milwaukee (64), Southern Pacific (58), Seaboard Coast Line Railroad (45), Nacionales de México (25), Long Island (23), and Louisville & Nashville (10), were all buying AC road locomotives. 36 more units were sold to 8 other customers.
The New York and Atlantic Railway operates approximately 270 miles of track in the state of New York. With a total of 14 locomotives, they operate a small fleet of ex-Long Island Railroad MP15AC switchers that are used for various tasks serving the lumber, plastic, food product, and waste/ recyclable industries. Even though they are a fairly small outfit, they haul an average of 30,000 carloads a year!
