EMD SD38AC

An EMD SD38AC is a 6-axle road switcher diesel-electric locomotive built by General Motors Electro-Motive Division between June and October 1971. It was basically an SD38 with an AR10 alternating current alternator instead of the SD38's normal direct current generator. It produces 2,000 horsepower (1,500 kW) from a 16-cylinder EMD 645E roots blown prime mover. It came equipped with or without dynamic brakes. This locomotive shared the same common frame with the SD39, SD38, SD40 and SD45. The SD38AC is basically the transition engine between the SD38 and the SD38-2. 15 examples of this model were built; 6 for B&LE, 8 for DMIR and one for BC Hydro.

gollark: I can help a bit I guess...
gollark: Stuff runs at those frequencies because the electromagnetic spectrum is pretty heavily government-regulated, with governments actually selling off access to most of it to companies, but most places allow use of 2.4 and 5GHz or so.
gollark: There are also different WiFi standards for packing higher data rates into whatever frequency range, some of which work, I think, by using several streams at different frequencies combined.
gollark: 2.4GHz and 5GHz are different, er, frequencies, though stuff doesn't run at exactly those frequencies but generally around them.
gollark: That's not really quite accurate.
