Atlas SD-9 and the different phases.

First of all, what phase is the Atlas SD-9?

Second, could existing Atlas shells make a convincing phase IV?

The DM&IR color book says the main difference between the phase III and IV is a taller battery box and short hood from the GP9.  It couldn't really be that simple, right?

So if the Atlas unit is a phase III it would seem a fairly easy bash.


Robbman, anyone?

Thanks,


Jason

The Atlas SD7/9? would be either Phase 1 or 2...

a Phase 4 would be a bit of work...

The big differences would be,

- Two 48 inch radiator fans instead of the four 36 inch fans.
- Taller Battery box under and forward of the cab on both sides (with the same size cab)
- Taller Short hood
- No battery boxes behind the cab
- First two doors behind the cab (on both sides) full height (they're blocked by the battery boxes on Phase 1-3)

Also the Missabe units had only one fuel tank. (with a weight & toolboxes in the location of the forward tank)

For Missabe, a Phase 3 unit would be easier to do (the only major differences being the 48 inch fans and the lack of fuel tank)

and for a really easy project 129 & 130 were near exact matches to the Atlas model, however these units were equipped for passenger service and did not stray off the Missabe in lease service that often, if at all...

Thx, for the reply.  I can see all that.  It is a bit of a list, but doesn't seem un-doable with some spare Atlas shells. I'll have to research if something can provide the taller battery boxes and a 48" fan (hatch on the other). Maybe I can come back with a more specific scenerio.  Of course with all that, maybe chop the nose and run it more modern.

101-130 were the same, right (except for the SGs on the two you mentioned).  I would definately be pulling the North-Star with those two units (I would need both to pull those B-mann amfleet cars anyway).


edit:  Was there some sort of filter box on top too?

101-128 were the same except 129 & 130 had both fuel tanks (one was used for water), keeping in mind that 101-128 were gone by the early 1970's (Transfered to B&LE and EJ&E starting in 1965)

The box on the long hood was a paper air filter retrofitted to a number of units. (Not sure which ones or when it was added)

Yeah, that's part of why I'm interested.  I want a second DM&IR locomotive and I'm pretty sure them IM is going to mess up the lettering on the 45-2's.  But with the delay now, maybe there is hope.

Microscale makes arrow decals with the UofMN lettering, could be an easy fix if the arrow is the same size on the IM model...

One other thing Chris's photos reminded me (btw nice shots of LTE ;)) during the SDM rebuilds the second fuel tanks were added.

Excellent, thank you. 


Is the generator compartment located right behind the cab on the long hood?

So would all that make the Atlas model the phaseIIb1?

I don't know if these help, they are SD-M's

Those are SD-18s that had the high hood replaced with a low hood. There's a thread over on the Atlas forum (or it may be the archives by now) about 2 years old about bashing SD-18s from SD-24s and SD-9 bits. I know because I made both the as delivered SD-18 high hood and the rebuilt SD-M with low hood at the time of that thread.

It's all Greek to me  :) 

I just looked up the numbers at RRpix first and they were listed as SD-M's http://www.rrpicturearchives.net/locoList.aspx?id=DMIR

To me they are 6-0-0-6's  ;D

Are these B&LE SD18's ? :

The SD-M Program Also used SD9's
