The SDP40F had steam generators - two of them. It was Amtrak's last locomotive so equipped, and one of the main hypotheses for its derailment problems was water sloshing around inside of the steam generators. The easiest way that you can tell this is an FP45 is the trucks (this model has the SD type, not the correct HT-C), the end platforms (SDP40F should not have a platform at the front - which is why ATSF had to cut notches in the nose when they added them), and the presence of a third set of carbody doors near the rear (SDP40F lacks these).
@@ErickC The trucks before the DASH 2 line was introduced in 1972, January was called Flexicoil. The HT-C trucks are 1foot 6 inches longer which accounts for the SD40-2 series having the famous porches.

The SD7 operator manual does refer to the trucks as "fully flexible," however. Take this in the context of the so called "Flexicoil B" truck, which EMD called a "Flexible Truck Assembly" in 1961. Nowhere will you find the term "Flexicoil" used in an EMD publication before the 1970s. My best guess? The evidence points to the term "Flexicoil" having been created when the HT-C was introduced as an extension of the "Flexible Truck" language and as a way to distinguish the new truck from the old.
I like those SDP40F's and the paint on the Amtrak. I find the same problem with the trucks and wheels on the Athern's. There's a lot of parts and a little trouble to get back together, but they work well. Maybe replace that contact bar on the top and solder wires on for better contact.
It runs more reliable than the real SDP40F's ever did. Also, fun fact 1 SDP40F still exists, but its in its Santa Fe Freight Configuration (SDF40-2) its currently at Boulder City, Nevada, owned by Dynamic Rail and sometimes runs on the Nevada Southern Railroad museum excursion trains.
The SDP40F was a superbly reliable runner, being an SD40-2 with a cowl over it and steam generators added. Its main problem was that it tended to derail at high speed on less-than-stellar track. The problem was hypothesized to occur due to water sloshing around in the steam generators, with some blame assigned to the HT-C truck, but the FRA later concluded that the issue was in fact the lightweight baggage cars that were being used at the time experiencing harmonic vibrations when coupled to this much heavier locomotive. It's worth noting that the SDP40F had no problems at high speed on ATSF track, just on the myriad of crappy eastern roads' equally crappy tracks. Ultimately, Amtrak decided that the GP40 was a much better platform, cut its losses on the SDP40F, and ordered the F40PH instead. ATSF took a bunch of the SDP40Fs and used them liberally for many years, where they proved to be every bit the equal of the SD40-2. Trivia: the SDP40Fs teething troubles were why Conrail ordered SD40-2s with SD trucks instead of HT-C trucks, which were a suspected possible culprit at the time, later disproven. Ultimately, all this did for them was give them a fleet of units with inferior adhesion to a standard SD40-2.
@@ErickC exactly! Once Santa Fe got ahold of these units and rebuilt them for freight service, they were superb units, many lasting well into the BNSF era! Another fun fact about these units they also had issues dealing with crew visibility so to rectify the problem, Santa Fe cut "notches" in each side of the nose which improved visibility out of the windshield. Made them really stand out from the crowd as well!
The notch was for a walkway on the front of the unit. Amtrak didn't see the need for a walkway on the front as they only used the SDP-40F's on trains where no switching theoretically was not needed.
Proudly to say i've had this identical engine you just repaired. I've had the SDP 40 since the 1990's! You did a good job repairing this blue box classic Athearn HO SCALE! 👋👋👋👋
Of course, she's a runner. Good old Athearn "blue box". My only tweak would be soldering a wire between the top of the motor clip and the tabs on the trucks. Maybe even a blob of solder on the bottom motor clip as well. But that's just me.
That's a great improvement for Athearn models before the Genesis Line. I know a lot of modelers that replace that power strip on top for better contract performance.
I bought the same exact engine when I was in middle school in 1977. It was my favorite engine. I kept it until 2004 when I sold it. Athearn Blue Box are incredible. I paid $27.00 back then that was alot.
Nice restoration on a cool Athearn blue box SDP40F Harrison! The real ones were lousy passenger locomotives, but at least they went on to have good careers on Santa Fe and BNSF! Glad Athearn eventually did make the the Santa Fe/BNSF versions, even if we had to wait 40 years to get them!
Looks like the FP45 body and as someone noted painted like a different model. Love the early "broken arrow" AMTRAK paint scheme. Like your repair videos=keep up the good work.
Roof fan arrangement says which body you have as they are quite similar but not identical. I have the same #503 as a dummy and my box says FP45 for a measly $13.75 (long, long ago in a galaxy far, far away) when I bought it at that price. Wheel base and axle spacing about identical to E6 or E7 bodies which means almost any drive from one of those (Hobbytown is a good one) could easily be installed in the Athearn body.
I wouldn't do that, the scratching it does on the wheels leave a place to collect carbon and the wheels never get really clean. Plus removes the plating. For an old Blue box you may not care; but as an FYi
@@jcure on the older blue box engines there is no plating. I do agree with you on the newer Athearn engine wheels that you should not use a wire wheel on plated wheels.
The Athearn BB model is an FP45 painted like Amtrak’s SDP40F since they shared a somewhat similar carbody style. Great to see the old large Athearn drive and steel flywheels in that puppy 😄
When you use its own power to clean the wheels, doesn't that risk getting grit into the gears? As to motor noise, I've been in the hobby since 1985. We spent years trying to quiet down DC models, then invested hundreds of dollars to add prime mover sounds to them with sound chips and then DCC. BUT, as you just showed, we always had motors that reflected load and speed, we just never appreciated it! 😉
Hahahaha, that's my sentiment on DCC sound exactly. Especially because not a single DCC sound unit sounds good because of the speaker size. It's just white noise with vague locomotive sounds buried under it.
The real ones were probably the most powerful passenger engines made at that time, at 3000hp. Seems their derailment problems stemmed from steam heating equipment mounted too high inside the car body- high weight distribution - and the combination of a light baggage car being coupled to a trailing SDP40F on curved trackage. The SDP40F is basically, a decendent of the SD40-2 freight locomotive.
The FRA later concluded that a combination of the baggage cars and poor track was the sole culprit (the locomotive never had a problem on ATSF rails - just on crappy eastern rails).
@@ErickC Thanks for the info! It was always puzzling to me. I know C&O and Burlington Northern banned them for a while, at least. Burlington Northern personnel called the locomotives, "track breakers," lol.
If it was a real SDP40F you would probably have to remove the water heater feature and replace it with HEP and probably some other modding to it so that way it does not crash and probably have to waste more millions to fix it again so that it can crash again (sorry for that long paragraph)
That's an older athearn because the flywheels are gray. most likely it will have metal wormgear's as well. very similar to my up gp38 might even be the same drivetrain. You can tell when they are newer because if you take one apart newer ones will have nylon wormgear's and brass flywheels.
They also have the older style of truck design where the bearing are located in the side frames instead of beside the gears. All the ones I've worked on have brass worm gears.
Great job on the repair. Almost all the locomotives that I can find that are under $50 have a noisy pankake engine. The fact you didn't and for $5 means you got a great buy.
Best thing to do with an old BB Athearn is get rid of the factory motor mounts and install after market screw type mounts and then get rif of the electrical wiper and solder in a piece of wire to replace it.
When he mentions its Athearn Blue box I am always like "Of course we can make it run". You really need to go out of your way mishandling an Athearn for it not run or at least try. There's a reason most manufactures use the exact or very similar drive system of the Athearn design, it just works!
Did you notice that the worm gear bearings are the same as the axle gear bearings? Good plan on Athearn's part in case you need and have spare parts to harvest from. John Kamloops, BC p.s. After cleaning the wheels, ya ought to remove the specks of dirt from the trucks, as the loco rattles down the track, those specks will fall to the rails and mess up your cleaning job.
You still didn't fix the top electrical contact, it was still out when you put the shell on, Slow down a bit and take your time so you don't have to go back and do things again.
Nice find...it would be hard to break an Athearn. The motor noise is better than any current sound system out there. I personally prefer to hard wire that top clip, soldering a lead to each truck contact, then to the motor brush cover.
Wow great restoration serenity! . I like how simple athearn is and they all pretty much have the same design thour out years. I believe the date code on the frame if that what 36071 is im thinking 71 is 1971. The other 3 numbers im unsure of . I know my athearn says 42005 maybe it's different on this model.
HEY! I have this same exact model, unfortunately she was completely gutted when I got her, even the gearing in the bogies are gone.. Shes just an empty shell that rolls, a bogus mount is broken, and for some reason i gotnthe engine with a different shell on the chassis and had to switch it out (I got it in an eBay box lot). Mine will most likely never run but it's good to see what it wouldve looked like in better condition, love the content!
I just commented on your mantua b&o pacific video, and this is another loco that I have that needs to be serviced. Mine runs well enough for the most part, but she sparks a lot at high speeds and cuts out on any incline
Also, the Athearn FP45 was first made by Athearn about 1970 and there were only 12 copies ever made, 9 for the ATSF and 3 for the Milwaukie Road. The SDP40F wasnot made until the late 1970s, as the prototype FP45 was mase by EMD in about 1967.

NEW Subscriber: Interesting. I've had good luck on ebay. I did go crazy on a brand new Athearn HO BNSF dummy. It was never used. Try to buy new stuff, out of stock. 👍 Thanks for videos. "A", I grew up in Michigan and now live near Fort Worth, Texas. Eaglegards...
FWIW, it's an FP45. I don't believe Amtrak actually had any, they were so new in 1971 that railroads who had them chose to keep them and send older E and F units to Amtrak. These almost never not run, although they can have a few minor issues. The oddest one I had was a couple of engines this vintage the bearings on the worm gears locked up and I had to free them up. It was a bit of galvanic corrosion I think. They ran fine after.
@@SMTMainline Athearn introduced these in 1973 along with the freight only F45. Neither one was owned by a lot of railroads (only Santa Fe and Milwaukee Road bought FP45s), so they invented a few fantasy paint schemes to sell more of them. Amtrak was one choice because of the similar looking SDP40F that was first built in 1973. But they also offered Baltimore & Ohio, which never existed in any form. Athearn was based in California so they tended to lean towards making things the western railroads owned.
The question was never "can" you get an old Athearn to run again but what was it going to need. I have one that had a bent frame as well; I took all the parts off and put it in a bench vise and gave it a few nudges to straighten it out.
This is a FP-45 painted Amtrak. Athearn blue box locks are super easy to work on and diagnose problems. The worst I've seen is an F-7 that was put together with what looks like salvaged parts. By the way would you like an Athearn F-7 blue box? It kinda runs, but isn't worth my time to fix. Is customs a problem for donations? Thx IGN
@@SMTMainline When Athearn produced these over 40 years ago they weren't going to bother making a "one-off" model of the SDP40F. Instead they just painted and lettered their FP45 in Amtrak phase 1 colors. They also sold these in Santa Fe "warbonnet" red and silver, Milwaukee Road, Baltimore & Ohio, Burlington Northern, Union Pacific, Pennsylvania, and Southern Pacific. Only the first two are correct, and the Milwaukee version is incorrect in that the real ones did not have dynamic brakes.
The rear top has components for a steam generator. That makes it a FP45. Athearn never made the SDP40F before the RTR or Genesis line.
The SDP40F had steam generators - two of them. It was Amtrak's last locomotive so equipped, and one of the main hypotheses for its derailment problems was water sloshing around inside of the steam generators.

Need to replace the metal power strip with a 14g wire btw the truck pick up towers and the top brass motor clip.
No he doesn't, the metal strip works just fine if its aligned properly.
It would work slightly better but the parts seem to be in decent shape and soldering makes the engine harder to take apart in the future.

NEW Subscriber: Interesting. I've had good luck on ebay. I did go crazy on a brand new Athearn HO BNSF dummy. It was never used. Try to buy new stuff, out of stock. 👍 Thanks for videos. "A", I grew up in Michigan and now live near Fort Worth, Texas. Eaglegards...
Oh my God lol favorite video now lol
FWIW, it's an FP45. I don't believe Amtrak actually had any, they were so new in 1971 that railroads who had them chose to keep them and send older E and F units to Amtrak.
These almost never not run, although they can have a few minor issues. The oddest one I had was a couple of engines this vintage the bearings on the worm gears locked up and I had to free them up. It was a bit of galvanic corrosion I think. They ran fine after.
Interesting to hear that. I wonder why Athearn decided to make them.
@@SMTMainline Athearn introduced these in 1973 along with the freight only F45. Neither one was owned by a lot of railroads (only Santa Fe and Milwaukee Road bought FP45s), so they invented a few fantasy paint schemes to sell more of them. Amtrak was one choice because of the similar looking SDP40F that was first built in 1973. But they also offered Baltimore & Ohio, which never existed in any form.
Athearn was based in California so they tended to lean towards making things the western railroads owned.
Dremel tool is a good investment
I agree
Fun idea for a project an engine roundhouse and turntablele
👍 cool
I have not seen that loco type in amtract
I have one of these and it runs fine but there no couplers on it and I don't know how to put them on. Can you make a video on it?
I love h.o Amtrak trains
The question was never "can" you get an old Athearn to run again but what was it going to need.
I have one that had a bent frame as well; I took all the parts off and put it in a bench vise and gave it a few nudges to straighten it out.
super que bonita locomotora
Sd-dash40 I think
I see
Did you reverse direction in which the trains run now for a reason?
I bet it might start and then stop
What did you put on the gearboxes when you were reassembling it? I've never seen anything white like that for model trains
If you can't get any engine running you can use them as a dummy engine use them as a second engine to look like a second engine is pulling train
This is a FP-45 painted Amtrak. Athearn blue box locks are
super easy to work on and diagnose problems. The worst I've seen is an F-7 that was put together with what looks like salvaged parts.
By the way would you like an Athearn F-7 blue box? It kinda runs, but isn't worth my time to fix. Is customs a problem for donations?
Thx IGN
epik
Hi smt when you going to have your friends over again that was great
For some reason on the box of mine it said "Amtrak FP45"
Apparently Athearn used their FP45s to mimic SDP40s
@@SMTMainline When Athearn produced these over 40 years ago they weren't going to bother making a "one-off" model of the SDP40F. Instead they just painted and lettered their FP45 in Amtrak phase 1 colors. They also sold these in Santa Fe "warbonnet" red and silver, Milwaukee Road, Baltimore & Ohio, Burlington Northern, Union Pacific, Pennsylvania, and Southern Pacific. Only the first two are correct, and the Milwaukee version is incorrect in that the real ones did not have dynamic brakes.
And your Amtrak SDP40F is missing it's horn.
It's clearly had a rough go.
@@SMTMainline Indeed.
What types of lubricants do you use? I noticed the Labelle 107 but what was that white paste on the worm gears?
This is the most realistic model of the 40F. It’s faulty, and…. just faulty haha.
The devil is in the detail, haha
👍
Mind if I ask you a question? What type of oil are you using?
Well folks in today's video...
😀👍
WOW
I have 3, 1 BN, and 2 Amtrak
That's nice
👍🏻😜👍🏻
Thats an fp45. Not and sdp40f

@@SMTMainline no. They look very differnt. Perhaps it was a mismatched box. Idk. But they r completly differnt looking locos.
🤝👍
It's an FP45
