    We have needed this for a long time in Train Simulator, and I’m quite surprised there hasn’t been an official release yet. The closest thing we have is SW1500. And there are many differences between the two.
    I thought of this because my friend and I made a New York and Atlantic Railway repaint of an SW1500 in order to use it as a filler for an MP15. Anyways, here is some history.

    History (Wikipedia)
    Switchers up to the SW1500 had been restricted to AAR type A switcher or Flexicoil lightweight trucks, both with a 96 in (2,438 mm) wheelbase. In 1973 60 special order Mexico-only SW1504swere built on a slightly longer frame, allowing EMD's standard Blomberg B trucks, with a 108 in (2,743 mm) wheelbase, to be used. In EMD's eyes (among others) this made the new locomotive a road switcher rather than a pure switcher, since it was capable of road speeds up to 60 mph (97 km/h) or so. 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 MP15AC replaced the MP15DC's DCgenerator 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. The MP15T uses a turbocharged 8-cylinder EMD 645 engine in place of a 12-cylinder non-turbocharged engine. The external appearance of the engine remains similar to other MP15 models.

    These locomotives would be perfect for road switching. The MP15DC could be made in Caltrain or UP colors for the Peninsula Corridor. An MP15AC could be used on any CSX related route in CSX YN3 livery. The MP15T could be for Miami - WPB in Seaboard colors.

    One was just released last week for the Cal Train route.

    MP15's are one of my favourites, next to the newer Genset 3GS21B units, and the GMDD GMD-1 built in Canada for CN and NAR.

    That was for Train Sim World, this is for Train Simulator 2020


    We could also expand on the MP15's and add any of the following roads for other routes

    Southern Pacific (Donner Pass)

    Missouri Pacific (Livonia Subdivision)

    BNSF (Stevens Pass/Marias Pass/Montana Hi-Line/The Racetrack)

    Norfolk Southern (N-Line/Coal District)

    Would love to see this switcher in TS! Really hope they would include the Caltrain switchers.

    Oh, sorry, must have gotten my forums mixed up.
