Triplex I saw you posted in the paint shop post. I just posted there , I was wondering how accurate those drawings are. Do you know, is this a good example of what you are saying about the athearn not being quite right? Thanks

I can't say if they're all of equal quality, but it was from those drawings that I learned how to tell an SD50F from an SD60F and an RS-10 from an RS-18. So I think they're quite good.

The Athearn isn't a DDA40X at all, but it looks very close to a DD35A. In fact, I don't know if there is a difference. Many people use it as a DD35A.

heres pics of my athearn dd40/35 (37.5)
The fans on top in the middle look like a 40 but the split fuel tanks it looks like a 35. Im a rookie so not sure what other things to look for.

I would think that a DD35A would have one small fan in between the 2 big fans, (on each hood) rather than 3 big fans. Don't know for sure. I would say that the Athearn DD40 is a never-built standard cab version of the DDA40X.

There were only 3 DD models, the DD35, DD35A, and DDA40X. The DD35 came first and was basically 2 GP35s back to back on a common frame, except it had no cab. They were meant to be run with GP35s in A-B-A or A-B-B-A consists. The DD35A was introduced later and is a cab version of the DD35. Since the cabless version was a DD35, the A was added to the DD35A to differentiate between the 2. SP had DD35As and DD35s, I don't know if UP had any.

The DDA40X was basically 2 GP40s on a common frame. It had flared radiators and a wide body cab. This is the UP 6900 series that is so famous.

The Bachmann model is a DDA40X. The athearn appears to have a narrow cab and flared radiators so it is either a DD35A with the wrong radiators or a DDA40X with the wrong cab.

According to "Diesel locomotives - the first 50 Years" EsPee operated 3 DD35s while the other 27 went to Omaha, along with the 15 cabbed units.

As for the Athearn DDA40X, it looks like 2 SD45 long-hoods with a '35-series cab: the flared radiators on the 12inch-to-the-foot one are stepped, not one depth for their entire langth. Maybe it should be dubbed the "DD40-and-a-bit":confused:?

I have to ask, why does everyone call it a DD"A"40X.

On both UP's site, and in my books, it is referred to as a DD40AX. I have alot of people try to tell me i'm wrong, but no one can find any EMD papers that call it a DDA40X.

Yeah, I had the owners wrong. I looked it up on Wikipedia after I had made that post and found that Espee had the first 3 DD35s. All the other DD35s and DD35As went to UP. Sorry 'bout that y'all.:rolleyes:

As for DDA40X vs. DD40AX I don't know. Shoot, I don't even know what the "A" stands for.

Don't worry, i shot myself down earlier today. It is, in fact, DDA40X. the "A" means it had a cab. if it didn't it was a boost. The "X" is for the centennial or something along those lines. Its basically just there to look cool.
