Email Scott with the request !!!!
Susquehanna Tunnel Motors, and SD40-2 as well.

@GG1 4877 posted:The closest tooling to this one would likely be the one that uses the Southern / N&W / Norfolk Southern tool of the high short hood SD40-2. BN units were mostly phase 1a2 production as are the high hood models listed above. Of course the cab would have to be removed, the number boards and class lights blanked, and the ATSF style plate antenna added to the top with some additional details, but not too difficult to model. Painting it might be the most difficult part. Tru-Color GN paints should match for the BNSF colors used on the BNSF factory units. Interesting units to be sure!
Already posted above, but my NS version for comparison with a closeup of the high short hood.
Jonathan,
Did you find any differences between the Norfolk Southern and the Burlington Northern, SD40-2? Were there any differences between the truck types on these 2 variants? I am unsure if the SD40 variants had different capacity, fuel tanks as the SD45 variants.
Before I read your informative reply, I had assumed that these SD40-2B were closer to the Burlington Northern versions as they were rebuilt from wrecked Burlington Northern, SD40-2.
These are just my opinion,
Naveen Rajan
I'd like a Kodachrome SP tunnel motor. Before I email Scott, would anybody else be interested in this scheme?
@GG1 4877 posted:Anyone in for an "AWVR" version?
Since the second run is a possibility, I know what I'm suggesting...

Promote this here but Always !!!!!! email Scott with what you’d like to see.
Tunnel motors are quite a bit different. Check out some differences in this picture.
So great that Scott gave us these variations on the SD40-2.

Write in MKT!
Are the intake grills on the tunnel motors not see through?
Here’s what I’d like to see added.
Comments here please. Emails to Scott if interested in Any of these. Understand nothing new is possible unless decent #s of people respond with messages to Scott with what they’d like to see added.
This is a pretty ambitious wish list. I’ll be tickled to see Any of these Added !!!!
This MP is different from run 1. It has dynamic brakes 
Step up with emails to Scott. We won’t see Any of these unless you
Speak Up !!!!!!!
It’s All about Numbers !!!!!!!!!!
Cheers 😉

Not see thru.
Hi Folks,
We announced a Rerun of the SD40-2s to satisfy the stand-by orders and any people that wanted some of the different road names offered in the first run, but couldn't buy them all at one time.
We are NOT going to offer any roadnames or paint schemes other than what was in the first run.
Your suggestions are great, but that would be something we would consider in a future run, 2-3 years down the road. A quick rerun is just that, using the same configuration drawings with the Painting and Lettering developed under the first run.
Any new road name require research for configuration, colors, obtaining color samples, having to go through many different processes before they can be added to a production run. This isn't going to happen on a quick 2nd run, sorry to disappoint.
Perhaps we will revisit the SD40-2s in years to come, with these added roadnames, but not at this time.
Thanks Again for all your suggestions. It's what keeps us going.
All our resources are being used to get ready for production of the following:
E7 4th Run: In production, finishing late Summer.
SD79 - Run #2 is coming later this year. Delivery by the end of 2024.
FA/FB - Early Next Year
Genesis and Chargers - 1st Quarter Next Year
Somewhere in this period of time, we can do the SD40-2 rerun, but we need at least 15 orders for each road name, and 200 minimum total orders to run the project. We should have that by the end of this year. If not, it will delay out further.
After that we are thinking of rerunning several of the other projects we have made in the past such as PAs, FTs, F7s and so on.
Have a Great Summer.
Great and Timely info-update Scott !!!! THANKS for the Guidance and some timelines !!!
We will keep our “powder dry” for some future Expanded SD40-2 offering !!! 😜
Cheers !!! 😉

It looks to me like the air intakes are louvers as opposed to screens. Do you know if this is prototypical for any tunnel motors? All models I have seen (any scale) and prototype photos I have seen of SP locomotives are screens. Its certainly possible that louvers may have been correct for certain locomotives or maybe as built. I don’t know enough about or have adequate reference material for this era of SP.
The radiator intake area on the all tunnel motors, the gp15's, and the mp15ac's are all mesh screens. There are no shutters or other components behind them, which is why they can be seen through. These locos do have shutters, but they are oriented horizontally above the radiator cores, in the volume that extends above the roof line.
The screen material is the same as that used for the inertial screens behind the cab, at least on late 1st gen locos onward. And for 2nd gen units like the dash 2's, after 1976 the same material is used for the radiator intake screens on locos with traditional radiator intake positions.
The inertial filter screens and typical radiator screens cannot be seen through since there are other components behind them, including shutters and cores in the case of the radiators.
The screen material and corrugations

Typical post 1976 radiator screens

All photos are my own.
I suspect that the intake screens are solid on the 3rd Rail models because there is a speaker or some other electronics sitting behind that part of the shell. Or it's a concession to the cost of tooling. Either way it's unfortunate that the screens are solid as they are a hallmark of the tunnel motors. Ironically, while I'm not a fan of tank drives, they would at least make it possible to have see-through screens without having a gearbox behind them.

Jim,
Thanks for the detailed information. The see through intake screens are a pretty iconic feature of the tunnel motors and your photo is what my memory recalls.
I’m more of a steam and early diesel guy but I have a fondness for certain 60s-80s vintage diesels and also being an SP and Rio Grande guy, tunnel motors are of high appeal to me.
This detail issue will probably have me sticking with Lionel tunnel motors and eventually doing fixed pilots on them. I love the 3rd Rail GP9’s I got and have SD7/9’s on order but its hard for me to spend $800 per engine with a major detail like this not being correct.

Any chance for FP7s lots of people have been talking about them.
I'd be in for Western Railway of Alabama/ Georgia Railroad FP7s and a Southern FP9 for my Crescent set.
It was a long wait but well worth it. These are my first 2-rail only engines running DCC and I am very happy with them. As you can see the accuracy and details are excellent but the best part for me are the sounds and that I don't have to move in the trucks, fill gaps, fix a pilot or even put on couplers because everything correct and ready right out of the box.
I really want to buy two more CSX dark futures but unfortunately, for whatever reason, that paint scheme was canceled early on. I'm surprised that is not a more popular paint scheme.
I'm new to DCC, if anyone knows how to turn off the second headlight in a consist, please let me know.

It was my decision to make the screens on the Tunnel motors solid. In the 3D image below, I made this section transparent so you could see what's behind the screens. One would see the electronics in one screen and bundles of wires in the other.

I think a wise decision. I personally don’t care to see the electronics or wires. I also think it also probably helps keep the inside more clear of particulates that can jam up “the works”. Of course - my opinion. 🤔
Cheers 😉

Then I am out until green MKT SD40-2's are made. I missed the MTH ones back in 2010. I've only seen one of those come up for sale on ebay and it went for the same price as a brand new Sunset model. I see the Lionel model come up occasionally but they made the green way to dark.
I'm pretty late with this but finally got mines out of the boxes. Special thanks to Randy for answering my want add to add another unit to make a trio of these great locomotives.
