GE Dash 9 Loco

GE Dash 9 Loco was created by Oil Slick
Hauling for BNSF I noticed the GE Dash 9 has a interesting shock package. On one side it 2 shocks on the front traction motor and no shocks in the rear. But on the other side has 2 on the rear but non on the front. So they only have shocks on one side in the front and opposite side only has them on the rear.

This doesn’t make much sense to me. Seems like all three axles would have shocks and on both sides. Any ideas why they might do it this way?

The shocks just help control the side sway or rocking of the upper frame when rolling down the track.

Shocks probably helped, but those engines still ride ruff on not so smooth rails. I

know because they kept me awake LOL

By the way what are you hauling for the big new Santa Fe???

Sounds like you are still working thru this virus thing. Not close to Amarillo???

Stay safe and virus free. To both of you.

See ya Claney

C, going from Barstow Ca to Belen Nm. Just went through Amarillo last week. No idea why anyone would want to live in all that wind. Guess it’s good for virus conditions cuz no one wants to go outside. LoL

I would have contacted you but I’m trying to be safe. We even disinfect the bottom of our shoes. Hate to track the virus inside and dog steps in it and runs around.

Thanks for the reply Rome. Doesn’t seem like enough shock for huge equipment but must work.

Your welcome! It's not so much as "shock" but more as stabilization of the upper frame, cab and engine from side rocking.

So Rome K/G

I guess Oilslick was "stumped" on this question so it only figures that you would have the answer with you being the "stump guy" on here!:)

I also see what appears to be a horizontal cylinder or "shock absorber" that would seem to cushion the truck movement as the engine goes around a curve. Any thoughts on why that is needed?

Actually, as I look at that whole design, I know that somebody somewhere knows a heck of a lot of what goes into designing a large RR engine than I do which is absolutely nothing!

Ha! funny Jan :smile:, That would also help with any sudden side shock or twist movement, sometimes you'll seen an old gondola car with a set of trucks that wobble like crazy going down the tracks at high speed, that's what this shock would help reduce.

Few more pics. I didn’t know they still had power only units without cabs. I’m a train watcher and never see them on the road. Must be only used as a switcher in the yard.

Hmm, yea they must use them [dummy engines] out west in the mountain ranges. Wow! that locomotive is about 55 ton heavier than a D11. No wonder it takes four 583H sidebooms to pick em up. Those are some big turbos on those engines, I wonder if they are a high volume and lower pressure turbo for the slower running engines?
