You think getting a EMD SDP40F replicated is a good idea? With the issues they had with the steam generators kind of worry me a bit or should they have HEP Generators? Let me know what you think.

Trying to buy something so it can be preserved can be a big challenge.
Here in the U.K. I am in a Tram Preservation Society. I wanted to buy a tram from Southport Council. They put up so many barriers it was unbelievable.
They finished up selling the tram for far less than I offered???
Good luck in your quest.

HEP, unless you plan on running steam heat consists. Picking up an SD40 as a base would be easy, then having the cab and hood replicated.
Yeah ill go with a few SDP40Fs With HEP Generators and some with Steam Generators.
Paints:
Phase I
Phase II
Phase III
(18 units total 6 of each paint 9 with HEP and 9 With Steam Generators)
The issues with SDP40F steam generators would be easily solved by adopting a different configuration for the water tankage; check with bogie_engineer on the best fixes for the trucks (I donât think the correct adaptations would âshowâ unhistorically from the outside).
I donât know if Dave Klepper is participating in the new forums yet, but he did extensive thinking about how to implement a revised AC-powered GG1. One approach considered was to build a modern equivalent (at the time, DC) to the existing twin motors, and then adapt AEM-7 main transformers and control circuitry to power them. If you contact the right people at New Jersey Transit in time, you may be able to swing a deal on stored ALP-44sâŚ
The âimprovedâ design for rebuilding GG1s in the mid-Seventies for high-speed service wonât help you much. We got around the frame-crystallization issues by proposing a welded replacement with chevron primary springing, which would look very different, and very substantial weight reduction would have been necessary to use them as anticipated with Amfleet stock (the problem was not acceleration, but braking, and if you dig around you will find pictures of the particular problem posed by braking from the ânewâ high speeds with those replacement-âMetrolinerâ consists â it was not at all funny at the time, but amusing as being soooooo predictable, in retrospect at this long a removeâŚ

And @Woke_Hoagland i contacted GE About getting one built from the ground up since its alot to get an original GG1 rebuilt to an operating state
âi contacted GE About getting one built from the ground up since its alot to get an original GG1 rebuilt to an operating stateâ
The most difficult part of âfrom the ground upâ would be replicating the large cast underframes, which WABTEC or whoever runs the GE locomotive operation now would have to obtain from a specialty foundry. There is no lack of capacity in the United States to make pieces this size, although there are some who would tell you so â the problem is GSC and its expertise in making one-piece beds are long gone, and youâll be paying full price for the learning curve to get an acceptable piece. The T1 Trust, for example, was quoted a figure for casting the frame⌠with zero guarantee that the first, or second, or later attempts at the very complex casting would be suitable for use.
In the Seventies, the frame would have been made of weldments and hydroformed plate. The modern version would make extensive use of lost-foam castings in appropriate alloys, joined by cut and formed plate, probably laser keyhole welded in controlled atmosphere. Neither would be particularly âprototypical-lookingâ enough to adopt the design for a modern locomotive.
Note that even PRR âback in the dayâ promptly went to an eight-wheel-drive design for a "T1 or two K4sâ equivalent as soon as a more capable traction motor (428A) came about â that being the stillborn DD2. (All the various kinds of locomotive wheel arrangement for the wartime electrification to Pittsburgy would likely have used these motors in that general construction; the specs in the proposal âmatchâ) I do not know if those motors are any more practical to âreplicateâ than twin motors for a pure GG1 restoration.
But even there, you have a large, heavy articulated frame, with four-wheel lead and trailing trucks that PRR determined were unprofitable to try to motorize (see the P5b) with a need for fairly competent slip/overspeed control. A GG2 would involve even longer frames, of course, and it would be as âfunny-lookingâ as a DD2 to eyes familiar with Dohner/Loewyâs original carbody.
The bill for a ârebuiltâ 120mph GG1 was on the order of $4.5 million each, in mid-Seventies dollars. That was in the era that one-piece cast multiwear wheels were required for new construction. While it was technically possible to adapt the idea of cheek-plate braking as on high-speed reciprocating steam locomotives, the quill drive limited the area of inside âplateâ that could be used, so the principal effect would only be to get rid of the evil of tread braking, which the new wheels would already have (from the standpoint of catastrophe) avoided. But it would still have been an enormous plumb bob at the head of an Amfleet consist â compare it with an 87-ton toaster with 30mph higher usable speed (for what was going to be a 150-mph-capable NEC by the end of the Carter administration, but thatâs another set of talesâŚ)
I hate to say it, but your best bet is going to be to restore the GG1 as an unpowered âdummyâ and fake the appropriate sounds (gear whine, tap changing, blowers, etc.) and put a genset and powered trucks on a converted express box or baggage car to actually run it. Gag the pans so they look like theyâre running at cat height.

Well, Ok but the whole unit itself would have been a ârevisionâ of the original model and with that fixing all the issues wrong with the GG1 but I donât know, we will see what happens I guess.

Should i do an SD80MAC in CNW paint since the CNW ordered I believe 15 or 18 SD80s? Iâm not sure let me know if I should so I can get that started.

Itâs not clear to me - do you actually have funds to make these purchases? How many donations have you gotten for an organization that has existed for four days?

The IRHS has gotten $1,500+ from locals in Norwalk who want to support the project and potential IRHS Grant, City of Norwalk Grants and one from the State.
and I believe Athearn has made a CNW SD80MAC

What Bogies/Trucks did the Dash-8-40Cs use? (D-8-44CW, D-8-40C, D-8-40CW, D-8-40CWM, D-8-40CWL, and so on)
Im thinking about getting majority or popular models of the Dash-8 series replicated or rebuilt as well

I believe they rode on standard GE floating-bolster trucks.
EDIT: Six axle Dash-8âs rode on Adirondack trucks, four axle models rode on FB2 trucks.
How many members does your organization have? Used, out-of-service locomotives will require a lot of restoration.
You do know that the GG1 is electric and requires catenary, donât you?
I would specialize in units that had some connection to your area when they were in-service. Look at the Mad River and Nickel Plate Road Museum in Bellevue, OH for an idea what I mean.
The Organization is made up of more than 50 People and I know that the GG1 is catenary, Iâm well aware of the out-of-service locomotive needing restoration, and Iâve gotten my hands on maybe 5 EMD GP9s that used to serve the CB&Q which originally ran in Norwalk before Becoming apart of Burlington Northern later being BNSF.
