The new model MP15DC designation thus meant Multi-Purpose locomotive, 1500 hp, DC generator. Originally the locomotive was simply designated the MP15; the arrival of the alternator/rectifier MP15AC in 1975 changed the name. With the success of the MP15, there was a demand for a model with an advanced AC drive system.
The point machine (in this case an electric motor) and associated mechanism used to operate this switch can be seen to the right in the picture. A point machine (also known as a point motor, switch machine or switch motor) is a device for operating railway turnouts especially at a distance.
The EMD MP15AC is a 1,500 hp (1,120 kW) diesel road switcher locomotive built by General Motors' Electro-Motive Division between August 1975 and August 1984. A variant of the EMD MP15DC with an AC/DC transmission, 246 examples were built, including 25 for export to Mexico, and four built in Canada.
Metra is the only railroad that ordered this model. The MP36PH-3S used a 16-cylinder EMD 645 F3B diesel engine as its prime mover , capable of generating 3,600 hp . Head-end power (HEP) was generated by a static inverter that received its power through connections to the prime mover (hence the "S" (static) designation).
A Heavy Duty model uses the 16-litre big-block MP10, the largest ever 6-cylinder engine from Mack, with 515, 565, and 605 horsepower (451 kW) models. The 605 has a torque rating of 2,060 ft⋅lbf (2,790 N⋅m) at 1,200 rpm. [2] It will replace the now retired CL model which served as Mack's "big bore" truck which was powered by the Cummins ISX.

In 1974 IBM started a project to build a telephone switching computer that required, for the time, immense computational power. Since the application was comparably simple, this machine would need only to perform I/O, branches, add register-register, move data between registers and memory, and would have no need for special instructions to perform heavy arithmetic.
