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.

Soo Line
After the 1985 acquisition of the MILW from bankruptcy, SOO inherited their MP15AC’s along with other motive power. While many were simply patched and put back into service, a few got the full white and red SOO repaint treatment. Even though we have offered these numbers in the past, we thought it was time to announce these again, this time with LEDs and Tsunami 2 Sound!
