DD40X dimensions

Good day everybody,

I’m new in this forum, and I’d like to ask if somebody knows the dimensions of the EMD DD40X (or where can I find them, if possible with diagrams). I’ve searched in the net, but I’ve only found the lenght over couplers and the wheels diameter. It would be especially interesting for me to know the width of this locomotive (both cab and motor hood).

Thank you very much, greetings from Germany,

Ariel

Big.

helpful as always, Max…[#dots]

i dont know the actual length of them, i’m afraid, but i do know pentrex made a video about them. you may want to look into that and watch the vid if you can find it

As I recall the book Centennials in Action has the drawings that would answer your questions, but I guess I got rid of my copy. If you’re really curious, http://www.abebooks.com has copies starting at $56.

I don’t have my figures, or a model, in front of me, but 95.5 feet over the drawbars rings a bell. Do a Google search for DD40X or check Wilikapidia.

OK, sorry for the delay.

The DD40’s are 98’5" over the couplers. Their top speed is about 90 mph. They weigh 545,432 lbs with two EMD 16-645E3 prime movers (2 stroke, originally rated at 7000 hp but down graded to 6600 hp because the injectors were burning up). They have 40 inch drivers, 8200 gallon fuel tanks and a starting tractive effort of 136,ooo lbs with a con tinuous tractive effort @90 mph of 19,800 lbs. I don’t recall the type of traction motors used.

They are big and stiff and appearently prone to hit the ties. By comparison, the current SD70ACe generates 4300 thp from a single 16-710G3C-T2 engine with 191,000 lbs of starting tractive effort and 157,000 lbs of continuous tractive effort (at much lower speed).

All this info and nobody has addressed the question. Here is what I have found:

I saw this loco operate 2 years ago at diesel days and it is a monster.

Now I found what I was looking for originally. This site should have everything you need:

Hi everybody,

thank you very much for all your answers, they have helped me a lot (even the “big” answer [:D], to confirm I was talking about the “right” locomotive…)

Have a nice day, see you till next time,[:)]

Sorry for the English measurements:

Height rail to top of engine 16’4" 5/8, to top of horns 17’3" 13/16

Cab width 10’4"

Coupler to coupler 90’5"

I have a photo of an information plate displayed with the engine that is in Omaha, Nebraska. If you blow it up enough, the diagram with the physical measurements is (barely) readable. If you e-mail me your web address, I’ll send it along.

Hi Dakguy, hi everybody,

it’s me again… I have another little question about the DD40X measures. In

http://www.thedieselshop.us/Data%20EMD%20DDA40X.HTML

i’ve found the following data of the DDA40X

Cab Width 10’-03"
Top of Walkway 10’-09"
Walkway Width 4’-07.5"
Engine Hood Width 10’-00"

Is there something wrong here, or is it just me, who doesn’t understand this? I mean, if the cab width is 10’-03’’ (or 10’-04’‘) then the engine hood width can’t be 10’-00’’ (that is too much!).
Besides that, I don’t understand what is the “walkway width”… I thought I did know what that is, but now (because of these data) I’m quite confused. Same thing for “top of walkway”… [D)] Can somebody explain me a little about these terms and measures?

Thank you very much, and have a nice day [:)]

Ariel

I think there was a walkway cutting in between the two diesel engines about midway down the side of the locomotive.
