I love the never say quit attitude. Keep it going

That was a beautiful job of ‘reconstructive surgery!’👏👏👏

Ah yes a very well known part of Canadian Pacifics roster

This thing belongs in the annals of mythology like Yeti and Sasquatch, rumoured but rarely spotted. That is one weird machine…😂

I am a deaf disabled veteran in SC. I have been watching you for a long time.

Keep your passion For Model Railroading Strong Harrison.

EMD: well no one ordered these so I guess we'll never have them. Atheran: * banging pots and pans on the front porch* COME AND GET IT!

Another big custom painted Canadian pacific dd35 is now a runner from parts! Serenity!

Another outstanding repair! CP Rail Frankenstein locomotive 👍

Mint salvage job! ♥️👍

First, there was the Canadiana DD35 now, there's the Canadian pacific DD35 we only need a Canadian national DD35 to complete the trio

Wow, Harrison, another DD40X added to the collection. Put a flatcar with Blinky, Pinky, Inky and Clyde behind the locomotive and run it in reverse. 🤣 Pac Man Fever. Thanks for sharing. 👍👍👍

Weird coincidence, I’m actually almost done with a very similar DD40 project right now. $1 is a great deal even for a broken one!

Athearn sold these for a long time. Single motor and with two motors decorated for a number of railroads that never had them. Never had them because EMD never built the DD40. EMD did build the nearly identical DD35 for Union Pacific and the DD35 cabless booster for Union Pacific and Southern Pacific.

Centennial of Canadian pacific. Epic video keep up the good work

Great video smt, I really need to catch up on these repair videos however.😆

"I'm just gonna pretend I didn't see that." - classic!! LOL

A DD40 for $1, the parts for this thing alone would cost an arm and a leg, nice score Harrison! Also the fact that these blue box locomotives are some of the most forgiving units to work on makes them a favorite among model train enthusiasts even today!

Great idea on the wooden drive shaft. I have a rivarossi JW BOKER 2-4-0 missing its drive shaft. I will definitely try a wooden one. Thanks.😁👍!

About 1980, I bought a junker at the local hobbyshop. Added pantographs, painted it Brunswick Greeb, decaled it for the PRR and had a Class DD3. Used on ore jobs out of Philly to Enola enroute to the mills in Pburgh

Amassing what you created from other parts

Two GP35 units stuck together to form the DD35 series. Now its a DD31? Interesting work, good video!

I looked at the face and I was like "Yep that's Burlington Route"

Super. I 💙 double diesels. ALCOs C-855, GEs U-50 and U-50C, and EMDs DD-35, DD-40, and DD-40AX are right up there, but my favorite locomotive is the Lima (Baldwin) twin V-8 powered Tr-2500 center cab diesel transfer locomotive. After reading all 254 comments, some of which had good info, and some not so much, just so everyone knows, this is a DD-40, technically a DD-40 A (Cab) unit, a model EMD had plans for, but never managed to sell even one to any railroads at all. (I wonder who Athearn knew back then?) An interesting fact is the first DD-35 was a cabless unit, and not called a DD-35B until after the cab (DD-35A) unit was produced, and then only by modelers. It was designed to work between two GP-35s, and the locomotives were officially known as DD-35 and DD-35A units and sold to the UP and SP, but they apparently forgot that "B" meant cabless. For the rivet counters, and easy spotting for the rest of us, the DD-40 and DD-40AX units have three large cooling fans for each diesel engine, while the DD-35 has two large and one small cooling fan for each diesel engine. (Edit: Also a dynamic brake fan for each set of trucks.) After EMD upped the GP-40s V-16 diesel to make 3,300 horsepower and designed and installed a safety cab and Dash 2 electrical components for the double diesel, UP ordered a bunch, and the Union Pacific DD-40AX 6,600 horsepower double diesel safety cab "Centennials" were born, which meant that the DD-40 was history. I much prefer the DD-35B unit as the roofline still looks like two GP-35s stuck together, without the extra large hump over the radiators, like the DD-35A, DD-40, and DD-40AX have. As to the one versus two motor comments, this locomotive was offered with a choice of one or two motors. (I'm not sure if non-motor DD-40 dummy units were available + who would buy a non powered version of the largest road diesel available?) Trust me, one motor was adequate to pull almost any model railroads entire inventory of rolling stock quite easily, but two motors added more horsepower, probably satisfied some egos, and allowed the locomotive to be heavily weighted, allowing you to pull 100 car trains without stressing the motors as much. Thanks again, an excellent video, and hello from the Tracy Mountain Railway in Colorado. 💙 T.E.N.

Interestingly, EMD never built a DD40, not even a demonstrator. It never left EMD's drawingboard. They went from the DD35s to the DD40X, so technically the model DD40 is a fantasy engine.

At some point I suggest replacing those soft motor mounts with the later screw on mounts. The older ones rot\perish and do not hold the motor firmly. Using the stick as a long drive shaft was genius. Great vid.

Well-done, Harrison.

LOL Harrison, cool save with those "Parts Bin" Stuff!! Too bad you didn't have another motor!! That would have been cool and it looks like it was made for 2! I hope someone can send you that 4 axle side-frame it is missing! So.... you need to do some more viewer mail vids. I can see my package under your table at 12:68 in the video. It's from C Widmeyer. I had a problem with C.P. not liking your address..lol Good to see it is there though. I bet you got a pile of mail to go through, but I think you'll like what I sent! Anyway, Cheers from Earl!!!

Model railroad wizardry. Nice job, SMT!

$1 is a steal for one of those. Nice ones are more like $50 US. Looks like a super early example, the handrail stancions have the stamped ends with holes. Those go away somewhere in the late 60s. Athearn based these on some EMD drawings for proposed models, is why it's a model of an engine that didn't get made. The UP Centennial is close, but has the wide cab.

This video just shows how you can use your everyday items to fix a train.

I didn't think heat shrink Would work because When you installed it directly on to the drive shaft there was no way for it to turn a regular drive shaft is loosely fitted and is able to turn

It's almost identical to the EMD DD35. The major difference being all the same size rooftop radiator fans in the middle of the long hood and the dynamic brake blisters. The EMD DD35 was two GP35 diesels back to back on a single frame with a common cab. It lacked the flaring at the middle roof line.

You gotta luv it. CP Beaver beast. Maybe CPKCS will copy this for their new railroad. AND it navigated the curves!

Wow .... Those gears looked really thirsty 😳

That’s a really fun piece. That paint scheme deserves resurrecting. Nice work!

Great job of custom building!

But...was it a single motor or a dual-motor DD40??? Looks like a two-motor model, but hey...you got it running with one motor - and she's running really quite well for an old gal!!!! And hey - using the wood dowel was a really neat trick!

That is awesome. The "Harrison Touch" works again, even on a Frankensteined repair. Incredible, Harrison, incredible indeed. Are there supposed to be any lights on it? Awesome video. Enjoyed watching. Thanks for sharing. 💜😊💜🇺🇸

I love old blue box Athearn. They're like farm machinery, they never get broken beyond repair.

The sound it makes generally scares me

Another great job doctor Harrison! very fun to watch!! thanks.!

....it's alive.... The Train Surgeon strikes again! Cheers!

Athearn did offer this unit in Burlington. As far as the motor, Athearn used the flywheels that were offered in the SW7 and S12 in both dual motor and single motor configurations with matching shafts to reach the worm gears. Also, the trucks are both the old and new style with the metal side frame truck being the old style.

This is an amazing looking locamotive. What a great repair for spare parts. Congrats on getting it to run.

For a fantasy loco, I like it. I can see a pair of them blasting across the prairie provinces on a transcontinental hotshot. Or lugging through the Canadian Rockies

Harrison you seem to be taking the Vice Grip Garage approved method for dealing with problems ( though with model trains rather than cars) and do the right thing and pretend we didn't see that. On behalf of VGG Nation I'll dub you an honorary feller. I used to dismantle those old blue box Athearns and give them the Harrison treatment right out of the box with a proper lube and white grease treatment, run a file over the gear teeth faces to smooth and mold separation lines and solder wire to replace the pick up clip and I got those 30 dollar BB Athearn locos running as quiet and creep speeds on par with 100 120 dollar Stewart locos. Evergreen plastics makes styrene rod of various sizes and one of the reasons why when I build models keep the sprues ( at least a couple old model boxes full) as there was more than a couple times I either dug out some Evergreen or sprue segment, notched a key in the piece to match the keyway in the worm gear coupling and MacGyvered a new drive shift. Being a pack rat helps. Used to pick up washers and bits of junk for weighing down rail cars and picked up 3 of these huge honking washers figuring one day I might need to do a special car or something but never did. Two weeks ago I'm building my late wife's Enterprise A kit and in a bone head move epoxy the darn thing sideways to the way it supposed to fit to the base and is now nose heavy, after a D'OH!! that would make Homer Simpson proud and some extra choice spicy words I dimly remembered something about those washers, dug out my old train tool box and in a move that would have made Scotty proud saved the Enterprise by counter balancing the base with the washers. Never throw anything away like that. Yep an old Burlington DD40 by those catwhiskers on the nose.

As several here have already pointed out, this is probably one of Athearn's most famous "foobies" - a model of a locomotive that was never built. EMD did offer a DD35, which was basically two GP35's on a single frame, with 4-axle trucks, and designed only as a cabless unit to be mated up with cab locomotives. SP had three. UP ordered them and liked them so much they requested EMD create a cab version, and thus the DD35A was born. EMD considered a double diesel version of the GP40 and it would have looked similar to what Athearn built from the concept drawings, but nobody ever ordered them and they were never built. Instead EMD created 36 of the impressive DD40AX, with its distinctive wide-nose cab. The first units were delivered on time for the publicity events surrounding Union Pacific's centennial celebration in 1969, hence their nicknames as Centennials. Athearn offered their DD40 in several road names, including CB&Q. The presumption that the unit in the video started life in Q livery appears correct. Somebody totally trashed the unit in trying to convert it to a CP dummy unit. Getting it to run was near miraculous as it was pretty much good for nothing but parts. The motor is incorrect. The powered models were originally sold (if memory serves) with the option of one or two motors. Neither were flywheel equipped. A Google image search for "Athearn DD40 diagram" will yield hits showing the exploded view parts drawings of the models. Athearn products are now manufactured overseas and they ceased all marketing and support for the old "blue box" models a few years ago to focus on their RTR lines, so finding replacement parts may be near impossible.

Amazing to watch you fabricate house hold items like the piece of wood to get those engines too run again. Great job 👏

Harrison u r a WIZARD. ! There not too many locomotives you can't fix.🥶

Hi Harrison. I really enjoyed this one, and the result speaks for itself. Hope you are happy with it

You can use your soldering iron on the tube to shrink it as opposed to a flame. I’ve seen that done on a couple other videos.

Way to go 👍 I really got to compliment you on that one after seeing that I believe you can do just about anything when it comes to train repair even making your own parts and getting that locomotive to run so superbly that’s pretty amazing 👏

I really enjoy your videos! Very therapeutic, if i was an HO railroader i could fix these little guys too! Nice work

I would really love to see you do a dedicated video on what oils and greases you use and when and where you use them. It would be hard to find that in a live video but if you made a dedicated searchable video that would be super helpful.

Hard to believe this locomotive was designed to go around 18" curves with truck mounted couplers. I remember the originals models had no flywheels, but we're available with single or dual motors, and retailed for $19.98, single motor. That may sound ridiculously cheap, but my first Athearn F-7A was $10.98 ($2 more for "super-geared"), and my rubber band drive "Hustler" was $6.98. My local hobby shop had a DD-40 in Great Northern "Big Sky Blue." I never acquired it, but it looked great in those colors.

Now that’s REAL modeling……👍

Hi its me again Hennie Schoeman from South Africa your way to fix trains is great im planing also to start but the hobby are expensive and its the best hobbie off all one's. More thanks

Locomotives in liverys I find these models interesting because I'd never imagine a locomotive that a company never owned in their livery

Thanks for sharing, I enjoy your vids VERY MUCH!! I learn a lot watching them,and they are so much fun to watch - PLEASE keep up your OUTSTANDING work & I've subscribed to your channel. can't wait for the next one!!THANX again.

GREAT JOB AT IMPERVISING on parts great for a Canadian dollar!!!!!!

Wow, nice work! Love your channel.

Wow very awesome. I got to say this is a testament to how Athearn was and still is a very good manufacturer. Nice work on the drive system put a wooden heart in for a driveshaft nice macgyvering that. Looks very similar to the dd40x but the nose is different. I love seeing stuff like this makes me think about my B unit that is a dummy and by Athearn I could make it pawered since it has the same thing electrical capability. Hmmm ideas ideas ideas.. Lol

Just amazing!

great video

I like the sound!

all it needs now is a sideframe and a few stanchions. 😊 that sideframe is pretty low relief, you could easily cast a new one, or even print one.

I've never seen that model before!

The axel set you mentioned is not necessarily broken off, it might have wheels from two different generations. Athearn never upgraded the DDs to inside bearings, so you might have an outside bearing wheel on one side and an inside bearing on the other. The peice you removed was a support for the long drive shaft that they used on the single motor models, basically the same as a band drive long shaft.

Nice Harrison

Sweet job on that! I'm working on a reverse de-motoring project myself, with an AHM Rivarossi berkshire that someone did an amazing custom paint job on, apparently back in the late 1970's if the '1977' scribed on the chassis plate is anything to go by. Parts seem to be rarer then frog hair for the Rivarossi berks though, so I've been scrounging Ebay and have even bought a second unmodified berk in complete condition so I can at least see what the parts I need look like for the custom one (and have a second berkshire, natch).

Awesome video ❤

Thanks Harrison very good work.

been awhile..but great to see a video again..take care and be safe:)

is interesting to see the various apsects of repair that you do:)

Great job smt!😀

With such a long engine maybe you should put another Pacman logo on each side.

This is super cool to see you rebuild this thing I did stuff like this whenever I had mine unfortunately most of my HO scale locomotives were junk or extremely old and out of maintenance horribly I did not possess the skills at the time being very young to properly do maintenance and revive these things so the ones that didn't work or I did not take care of very well ended up failing I'm afraid and I ended up having to cannibalize some of them I actually made a locomotive with two drives at one point it was one of my favorites because it was basically a Frankenstein but it worked so good though I did an amazing job for the time at least I thought I did it was built out of basically a bunch of broken scrap parts on the outside it still looked all right but on the inside it was a total mess but it worked really good I'd love to see you install a second motor would be pretty cool

Waiting patiently for your next video, and here it is

Have you ever heard of the Seminole gulf railroad?

Great video and keep it

Nice work!

You are Master Craftsman!

That's more like a DD35A

Hello Harrison enjoy the show; if you take a file and gently file the soldering tip, you can restore it just be careful you don't break the tip. By removing the old soldier residue the soldering gun will work better.

That whirring sound you hear is Ole Irv Atheran doing about 3600 RPM in his grave.

Glad to see that you were able to get it running Harrison. However, I think you have it wired or setup backwards. If I'm correct, once you put it with another unit you will find that they will run in different directions. To correct this, rotate the trucks 180% or put the rear truck in the front and front in the rear.

Extraordinary.

There is a real locomotive of a DD40X and it was a Union Pacific locomotive and there is a good amount of history about this style of locomotive.

that cheap body paint is a giveaway

Hello Harrison how you doing I like how you took a dummy engine into a working engine that is cool to me it was very interesting to watch your video

You are a genius!

The metal railings are definitely worth $0.82 usd! 😂

Hello Harrison, nice Job again and the good thing is that you don't have to use a Sound Modul. The Engine makes it one sound. Greetings from Bruno

Athearn DD 40 cp looks cool. My DD 40 has 2 motors. In UP number 70

Been enjoying your videos for a long while. What I think you need to get is a 3D printer to design and print all the missing bits you need

5:56 I'll steal that idea, i want to test if the elasticity of the tube makes some noticeable difference on starting and stopping, like a condensator in the motor.

What are the blue tools you use for cleaning motor gaps? Brand /model would be appreciated. Your videos are excellent.

You got another? Share some with us, dang!🤣

You can get higher wattage tips for the iron. I think the one with a little broader one works best for me. If the Heathkit Company was still around you could get great soldering experience putting some kits together. I even built a television from them.
