I was talking to a r.r. engineer saturday and ask about his experience with the cat loco's.He is not happy with them,he say's the vibrate and shakeand not a pleasure to run, I know this does'nt pertain to what most of us play with,but it's like someone bad mouthing your family,He is a good friend did not mean it personaly,but most of would expect the best out of Cat. just my two cents Gene

Interesting comment. Just curious. Are these Cat engines another engine option in a existing series of locomotives or is it an all new locomotive series. I wonder if its all engine vibratation and shake or if there is other factors telegraphing through.

I wonder if it is an older EMD Chassis? Big Slow speed engines have a different vibration than a smaller 3500 series turning higher RPMs. A lot of work has gone into newer rail engines to isolate the engineer cockpit/cab from the rest of the engine. Not sure where EMD was in this process?

I would think the vibrations are coming from something other than the engine. Any engine of 6 cylinders or more can be and are internally balanced. Do you know which locomotive he was referring to with those comments?

Aloha in 1973-74 i was employed as a motorman in the Henderson west tunnel project in Colorado we had as yard locomotives 2 15 ton cat powered diesel locomotives im not sure of the size big 6 cylinder jobs.On the run up the dump pushing 13 heavy muck cars the exaust side of the turbo would glow orange hot . We would set the throttle wide open in 3 gear & open the door to engine & get close to that hot turbo to stay warm as it was often 20 - 30 below 0 lol the good days.

Cat has owned EMD since about 2010, bought them from Berkshire Hathaway (Warren Buffet) as I remember...GM spun EMD off several years before that.

I ran a Cat powered loco back in the 80s I think it was. Cat installed engines in three locomotives. they were the GP ( jeep ) type with 6 axles. They ran

a lot smoother than the old emd's and a lot less noise. I worked for ATSF and they were running them from Chi to Barstow or San Bern. It wasn't long

before they disappeared. Don't know what happened to them. They were either 12 or 16 cylinder. Probably 12. Seems like they always came thru Amarillo

at night so couldn't see too much.

I know the UP has some Cat-powered locos. My friend that works at the Cathouse here used to go to the railroad yard to do tune-ups on, I believe, 3516's in locos...he was kind of a 3512 & 16 specialist, the oil patch has a bunch of them...
He has since graduated to service advisor, so no more big engine stories...but he does have an unusual piece of yard art-a 3516 crankshaft...
