I would shy away from using the DDs on the Mountain Division. I think the curvatures would be too much. I don't believe the line can handle SDs, so the larger truck would probably be a no-go. I did think about that but like I said I am pretending they completely revamped the line, although Crawford notch is sooo tight they would have had to shave half the mountain off to make a better curve for six axels and up. Ill think about it some more. I really did at least want ACes on that line.

6-axles with steerable trucks could probably work over the notch so you can get you ACes, but I would keep the DDs to the main west of Portland (or perhaps Waterville).

There is always an alternate reality where this is totally feasible. Take a look at the DDM45 built out an SD45 and DD trucks for use on a narrow gauge railway as a way to utilize the full power of the SD45. That's a good starting point. If your railroad is going to rebuild them in 2015 (probably after previous rebuilds) then this is a good time to incorporate some technology that is *almost* available...ceramic diesel prime movers, amorphous metal foam for frame repairs making the frame stronger than the original and advanced digital control. You might add flared radiators like the SD80MAC and rearrange the the air intakes. Take a look at McHenry MCH52 couplers, they look a little funny but they totally work giving you the ability to run on 22" radius curves. I have a similar project on this board where I put a MP15 cab on a DD40 at dieseldetailer.proboards.com/thread/15223/mp40ddax?page=1&scrollTo=105701

I say go with the DD trucks, run the sucker down the Bucksport Branch on your layout, and tell any nitpickers that the weight and long wheelbase trucks help keep it on the rail!
(For those who don't know the area, the former MEC Bucksport Branch is somewhat infamous for frequent derailments due to very poor track conditions).

(For those who don't know the area, the former MEC Bucksport Branch is somewhat infamous for frequent derailments due to very poor track conditions). We run six axle power to Bucksport on the club layout on a regular basis! The only reason a DD never made the trip is I don't recall one ever being on the layout. As for knowing the branch, I grew up about 500' from Milepost 17, right near the top of the grade out of town. A shame the mill is now closed...

As I said earlier... make it a GENSET or a ECO ! Some GENSETS have Fans on the long hood.

It would make a really sweet GENSET, I might have to do one of those myself....about 6-8 huge fans on top...that would be nice.

The DDA-40X was built with flaired radiators......

SNIP You might add flared radiators like the SD80MAC and rearrange the the air intakes.

Here is something to research....the MILW SDL39 had C trucks to distribute weight in the same way a Tank or Fighting Vehicle does with the width and length of the tracks. The DDM45 was built to do the same thing. Consider rebuilding a DD40 with 2 sets of flared radiators all at the rear instead of the middle. Also assume that instead of the 2 prime movers you rebuild with a single super large prime mover. Add two extra large fans at the front behind the cab and remove all the other fans between the front fans and the rear set of 2 modern flared fan sets....also assume that frame cracks are fixed with amorphous metal foam. The DD trucks distribute weight better down to about 30t per axle and a horsepower in the range of 7-8k....make it a monster SD9000
