    Looks like an upgraded, downsized Fairbanks-Morse. FM powerplants were used on marine applications, especially US submarines. Which led to FM railroad locomotives.

    You beat me to the punch here.

    I was going to state the same thing. Looks very similar to the Fairbanks-Morse submarine engines, which lead to use in railroad locomotives.

    I was only aware of this style of engine being used in the FM Train Master.

    Are you aware if this style of engine used in other US railroad applications?

    Did you look at my photo? switch engine HH600, H660, 10-44, 12-44, 16-44. Road switchers 14-66, 16-66(CNW "Baby Trainmaster), 24-66(Trainmaster). Passenger full body "Erie Built" and C-Liner. Numbered models were by HP, then powered wheels per truck. 44 means 2 traction motors per truck. Keep in mind that the wheelsets are basically a solid drive axle. The current EMD rail diesels have 1010 Cubic inches per cylinder! FM contemporary engines were 567 cubic inches per cylinder with 2 cycle process and a roots blowers. The 1010 engines are now 4 stroke. GE has a 952 inch cylinders in their current models. Yeah, I'm a train nut too! And FM power units are STILL made and used in marine apps.

    Sorry, didn't mean to offend.

    Not sure what photo you are referencing, this is what your post looks like from my browser.

    None taken! The photo above my name. me at the throttle. Glad to have been able to enlighten. I just kind of wish that I HAD done the CNW instead of Corrections. I would most likely be in better shape now. 25 years in a job where you can get beat up on any given day kind wears out your knees and shoulders. I was lucky, I got out with most of my mind and body intact!

    The Emergency generators on the Enterprise (CVN-65) had many of the same characteristics (2 cycle, opposed piston, roots blower). I wonder if they were relabelled or ??? maybe my memory too. It's been 25 years.

    Sorry they were GM diesels.

    I should have clarified the Enterprise's Emergency Diesel Generators were GM diesels but they had a lot of the F-M diesel characteristics above.

    51, 73, 92 series or maybe EMD straight out of locomotive style? All including, non turbo loco units were two stroke with Roots blowers.

    I seriously doubt whether a 'stock' body, frame and normal transmission system could get anywhere near 37 mpg, no matter what engine was used. Too much wind resistance and friction in the gearing.

    Not to hijack the thread, but since it's a version of a single piston opposed cylinder design (maybe a 'flat' engine?), let me mention the Mery Engine developed in Chico in the 1890's or so. I first saw it in at an engine show in the mid-1980's and got a copy of the patent for the owner, Bob Patty.

    The opposed piston seems most F-M.
