Athearn made the GP9 (actually a GP7) kit for over 40 years, but the first version was only made from 1957 to about 1960. In this video, I build that original model and then go over it in a review!

All things considered, given these are nearly 70 years old, they really don't look that bad. I am 62 and remember these well as a kid. Also seeing all the superdetailing that was being done back in the 70's especially. It is almost as if nobody noticed the fat hoods until the Atlas/Roco GP and SD models came out in 1975!

I loved that paint scheme of the Southern Pacific and also the red noses. I use to see Athearn locomotives and rolling stock in the boxes on a shelf at my local toy store back in the earlier 1990s thru 2007 before it closed its doors. I wished I would have bought some since they were at a decent price. They looked cool to build, I like the nostalgia of it in my older years. I was young and really didn’t have an interest to sit still long enough to build anything worth my while. Great video to learn something new. Perhaps I’ll find some at a train show to build one myself 😎🚂💨💨💨

Great build, Its sad the old Globe drives aren't as known about today. They're a great option for repowering with a can motor if you want a heavier chassis in a custom build. I would like to point out, the long bearing in the top of the gearbox is actually two of the drive axle bears pressed in either side. Found that out accidentally during a service. Hope to see more builds in the future!

Good video. I've never seen one of these early Athearn geared drives. I've only messed around with their rubber band drives of the same era. I've started using J-B Weld two-part epoxy for the metal handrail stanchions on my Athearn diesels, both where they fit into the plastic body shell, and where the stanchion meets the handrail. No more crooked stanchions!

Super. I operate four Athearn GP-9 "Bluebox" locomotives that I bought almost fifty years ago, and just by chance, they all came with the Jet motor and later version gear drive. I never knew that there was a third type of drive for the GP-9, not just the band and jet drives. The trucks remind me of the Mantua/Tyco MU-1 power trucks, with all the screws. I also make sure that all of my locomotives have winterization hatches, dynamic brakes, nice horn, and a full lighting package. 💙 T.E.N.

My first locos that I got when I was 4 years old were a GN GP9 and an NH F unit, both rubber band drives. Soon after, I got for my birthday, one of the units like in your video. The motors were pretty weak in all of them, and I don't remember where I got a replacement from a few years later, but it had about 3 times the torque the stock motor had, and improved it in every way. The amount of screws in some of the old locos always impressed me for some reason. I have a couple of RC cars now and the bigger ones have literally 200 allen screws holding it together.

Enjoyed the video! Did you consider swapping in a modern (presumably better performing?) motor, or is it your practice to keep the model as "stock" as possible? Similarly, is it possible to retrofit the model for eight-wheel electrical pickup? Also, you mentioned that hard-mounting the motor to the chassis helps the motor run cooler. Do you think it increases the running noise, though?
@DarthSantaFe8 ай бұрын
Thanks! I’ve upgraded a few of my Athearns with better motors, but this one will keep the original motor for the history. It is possible to upgrade this to 8-wheel pickup by installing some wipers to the trucks using insulators. The process is actually pretty easy. Having the motor directly mounted does increase noise, so both methods have their advantages. The motor noise isn’t a big deal in this one, but I do like to soft-mount the motors in models with really quiet gearing.

I decided to do some quick internet research on the winterization hatch. While I didn't find it on any SP GP7 or GP9s, I did find them on UP and WP locomotives. Other details that would stand out the steam generator and dynamic brakes. The UP, WP, and the SP had dynamic brakes, but the steam generator were hard to find. The reason that I choose these railroads were due to Athearn's closeness to these railroads and it was rumored that somethings were based on SP prototypes. My best guess that Athearn created this model off of some EMD drawing or even something that Kalmbach Publishing. provided. I would say that if the winterization hatch, the dynamic brakes, and the steam generator was left off; it would be more of a generic model of the GP7 or GP9. Who knows? Uncle Irv may have like these details, and this is the reasoning these details were chosen.
@kriscarver-seaboyer92048 ай бұрын
The Athearn GP7 was always designed to have the dynamic blister be removable. At the time it was tooled, it was assumed that most modellers possessed the skill to removed the cast in dynamic fan, and to be able to fill in the resultant hole - but they did you a solid and made sure the hood radius stayed correct under the individual blister pieces.
@tracynation28205 ай бұрын
You could have your brake and delete it too. The Lionel HO GP-9 complete dynamic brake blister fits the Athearn non-dynamic GP-9 and the Tyco GP-20 perfectly, as well as other locomotives. (NYC was the only railroad to have non-dynamic GP-20s.) 💙 T.E.N.

Once things are cleaned, try turning the driveshaft on each truck by hand and see if you can feel any binding. If the mesh between the truck and gear tower is too tight, you can insert paper shims under the gear tower until it turns freely. Beyond that, I'd mostly just be sure everything is properly cleaned, oiled and moving freely. You can check some of my Hobbytown videos to get a good idea on some parts since they're built similarly.

With that, my guess is the gear drive was introduced in 1955 or 56, the Hi-F was at least advertised in 56, and everything was in full production by 57.

How do we know we have a GP7 and not a G9? Back in those fragrant days of yore, fans and modelers would have told you a GP7 had no dynamic brake hump and a GP9 did. Simple and WRONG! When GM finally got on the roadswitcher bandwagon in 1948, it took the prime mover of the F7 streamlined freighter, the model 16-V-567B (16 cylinder, V configuration, 567 cubic inches per cylinder) of 1500 horsepower and its associated electrical equipment and put them in a roadswitcher car body. In 1954, EMD introduced the GP9 with the 1750 horsepower 567C engine which, importantly, solved a problem of the B - which leaked water internally. Oil diluted by water does not lubricate very well. Downed locomotives in the shop were eating money = unhappy customers (EMD developed a modification kit for the Model B that the railroads could install, creating the BC engine, and solving the problem....for a price, of course, GM wasn't running a charity. There was an A to AC conversion as well, but few people ever bought that, why spend money on an old locomotive due for replacement soon?). The F9 sold OK, but the GP9 became world beater. With a reliable engine and "a simpler electrical system than a '56 Chevy" it stayed out on the road earning money rather than in the shops consuming it - and it could do any job the railroad asked of it, passenger, way freight, transfer, fast freight, switcher. More GP9's were built than any other diesel in history (4257) - a record that stood until the SD40 and its derivatives came along, two decades later. The kicker in all this is that both GP7's and GP9's came with and without dynamic brakes! Beyond looking at the builder's plate how can we tell what we have? Easy! Look under the cab. GP7's have three sets of louvers in the battery box, GP9's have one or none. GP7's also have two sets of louvers at the far end of the long hood, GP9's one or none. Congratulations! You are now on your way to being a diesel locomotive model expert, impressing your dinner companions should the subject come up and winning bets in bars. I'll let you figure out what model Espee 5600 is. BTW, it is in the as delivered "Black Widow" paint scheme, the "Bloody Nose" livery (Gray with crimson ends) was introduced around 1960. PS - the louver ID method is based on how EMD built them. In the three quarters of a century since then, &deity knows how many shoppings, modifications and rebuilds can have altered things on what is down on your local short line's ready track..

It was actually a Lionel error that hit propagated into the model railroad world for almost fifty years. They sold the non DB model as a GP7 and the dynamic equipped model as a GP9. Athearn followed suit, calling their model a GP9 even though it’s a mish mash of GP7 phase differences (it could be seen most accurately as an late Phase 2 model once the full length batten strips are modified).
