Are they related to 86' hi-cube with two sets of double doors on each side? Those look sort of similar to me...

They might share some parts, when I do get around to making those I'll probably start with what I have already. This is going into the fourth car I've made using that 60' ACF boxcar as a base, so I'd say that was a pretty good use of my time.
I'll second that. Those hi-cubes have always been a interesting car to have around.
Awesome stuff! It's good to see that his free-lance work is continuing after he left Blizzard. Hope to see a plethora of his work for T:ANE (or sooner).
Finally, the locomotive Danny was alluding to in a e-mail he sent me! Looks very nice!

im just asking but did all the ac6000cws have the double smoke stacks or did some them have a single smoke stack
norfolksouthern37
what's a normal map?
some were converted to 4400 hp FDL engines, those have a single stack.
The 6,250 HP 7HDL-16 engine had twin turbochargers, therefore twin stacks. The 7FDL-16 has one turbocharger, so yeah. CSX has been transplanting 16-cylinder GEVO engines with 6,250 horsepower into these units and I believe they still have a single turbocharger. To further expand on Justin's reply, UP decided to replace the 6250 HP engines with the older FDL engines because the HDLs were snapping crankshafts and there were problems with the twin turbochargers.

I was never crazy about them, but figured I might as well. Glad I did!
Or.... UP took orders on a GE unit that was talk, and was not an existing working prototype unit. What happened, is the first batch was actually using 7FDL-16 (Same ones found in AC4400CW's) and they would send them small moves at a time to be converted to the 6,000HP motors. Well, the first batch of true AC6000's were horrible, so bad, that there's a decent number that just never got converted. I think other than about 3 or 4, anything UP with the AC6000 body-style is really just an AC4400CW.

That's interesting. Are there any figures on the savings that the UP got from decreasing the HP on those units in terms of maintenance costs and time out on the road vs in the shop?

The GEVO-16 engine still has twin turbo - that is, one turbo for each cylinder bank.
It wasn't that they were decreasing power but putting totally different engines under the hood (the tried 7FDL16 that didnt break as often for a variety of reasons).
The 7HDL16 was a derivative of the natural gas Duetz MWM632. GE/Duetz modified the design to make the large 6250hp engine suitable for rail but the design was plagued with trouble. GE won a big lawsuit against Deutz for not reaching deadlines and reliability standards. After that failure, the basic HDL design was improved on and made more reliable and that design became the GEVO series.

I see. Did CSX do anything to theirs, or did they remain the same from when they bought them?
I remember the AC6000s used to run into Boston's Beacon Park yard frequently before it closed. Now that the Boston Line is truncated at Worcester, I believe the AC6000s were transferred to other divisions.

Yes, I know. Some are even being converted to traditional AC4400s, by carbody style because the twin radiator fans are no longer required. The original 6000 hp units ended up being the ones that got converted back, yes. UP no longer has any 6000hp GEs on the roster.
That's interesting. I never knew they modified a natural gas model. I do find it interesting how the ES44-series was slightly inspired by the AC6000s

Some of them were converted to AC4400s but then converted again to AC6000s with the introduction of the GEVO-16 engine. All of them are 6000 hp again.
