Through mergers and lease agreements, UP acquired quite a few MP15AC’s. By the 2010’s, the paint was showing it’s age and UP started to repaint many of their locomotives. They added barrier stripes on the ends, added yellow frame stripes, and used a smaller lettering font size. Many can be found operating around yards and terminals.

New York and Atlantic
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!

Southern Pacific
Looking for heavier road switching power, SP turned to EMD in 1975 for 58 MP15AC’s to add to their roster. A small batch, #2732-2735 were used as slug mothers mated to a rebuilt EMD switcher slug for use in Roseville, California. Many of them were absorbed into the UP at the merger. After their tenure on the UP came to a close, quite a few found service on lease fleets and short lines still seen operating today.

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!

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.
