ex-EMDX 3....

Wow !!!

Thanks for the info. It was the only engine that kept on popping up in a search and I guess now I know why. Supposedly the trucks under EMDX3 were a little shorter than production SD-70 trucks. So, that would be a truly unique modelling opportunity.

SD60 and SD70 with same truck wheelbase

SD60 and SD70 both had a truck wheelbase of 13'-07''

2"

What I have read said they didn't change it much, something like 2". It had something to do with the difference between some of the original DC equipment and the new AC stuff.

Interestingly, supposedly, GE's Dash 8-40C still whooped up on even the SD60. As with most other models, the Dash 8 is almost all gone in 2017. Many of the SD60s are still around, albeit stored as surplus.

Question regarding addressing

GMTX 9041 would be easy to address in DCC. If I painted this model as EMDX3, what would you make the decoder address? I mean the address 3 is default for every non-programmed decoder, so I would like to avoid that one.

333?

How about 333 (for x3)?

not all radials are the same

333 ?

x3 = 333... Very creative.  I'll probably paint it as GMTX 9041, but that is not a bad idea!

GMTX 9041 definitely has 40" or 42" wheels. Funny you mention all those variations, Scott. As I was making the original post, I wondered if the trucks were the same on all models.

Trash 8's

Yes, most of the 8-40C's are gone, but the 8-40CW are doing just fine. Most on NS have been upgraded with the same FDL-16 found in the Dash 9's. The majority of the standard cab SD60's have been rebuilt into the SD60E with the Crescent Safety cab. The SD60M and SD60I's are also still on the roster out earning a living everyday.   

Oh, that's interesting...

I did not realize the CWs were still around. Not really having a favorite prototype, I thought I was going to have to start painting CN because they seem to run A LOT of Dash 8s. I have several old Railpower Dash 8 CWs. If anyone could tell me how to fix those terrible front windows, I would do it, for sure.

So the SD60s have been upgraded to AC or are they still DC with upgraded electronics to keep them from burning up? What about all of the old SD40-2s and all the other first and second gen EMDs? I understand AC can run with DC the problem comes in when there is a continual high amperage demand from continuous grades or these ridiculously long trains some railroads are running.

Back to the original post, does anyone know if GMTX 9041 is still around? I like those "one offs" and feel like it needs to be modeled on my railroad.

Google can be your friend....

Well now, what do I do ???

That is cool !!! I just can't decide which paint job to do... GMTX9000 would be easier than 9041 if I could find the New England related details, but then that localizes the engine.

Searching for that engine, I did find a couple people commenting about how it was an SD70 because of the trucks.  Not true, so I think that gives a little more reason to model it. It would be a great talking point at an open house.

EMD SD60

The EMD SD60 Series have DC traction motors. There are 3 types of SD60 locmotives, SD60 with the standard cab, SD60M with the safety cab and SD60I also has the safety cab but includes some cab isolation. If you look on the short hood of the SD60I you'll notice a gap in the nose that has a rubber insolating piece in it, this was suppose to help reduce vibration in the cab. They say a photo is worth a thousand words, so here goes:

SD60 Standard Cab.

SD60I (Separation in short hood just behind sand box cover and in front of grab iron)

SD60M (No separation in short hood)

SD60E (Standard cab SD60's that have been converted to the Crescent safety cab)

Yes you can mix AC traction motor and DC traction motor locomotives now, because the DC traction motor locomotives have been equipped with traction motor protection panels.If the DC motor is stalled for too long a period of time, the panel will try to prevent harm to the motor.
