with added Hobbytown "multidrive" kits you can power more than one unit with a single motor vastly increasing the pulling power. The multidrive is simply a system that powers trucks in a second (and even a third) body via additional trucks and universals (similar to yours) but not a second motor. All underneath leaving the second (empty) body to hold electronics or sound systems.

Always liked that black widow livery

Random Model Company: Makes a F7 unit Harrison: ILL TAKE YOUR ENTIRE STOCK

When you hear that “Wellll, folks” of in the distance, you know it’s gonna be a good day.

SMT like your videos . It really helps me when people on Facebook ask me about manufacturers . And I tell them about your channel .

Definitely worm gears. Serenity now

I'm collecting the parts needed to complete a 2026 Lionel engine, I'm gonna send it to you in pieces thought. I already have 2 so I figured I'd send you my donor one so you can have one too and I'm sure the good ol' folks would like to see a video of you putting it together. cheers bud, nice repair video!

OoOoO Southern Pacific. Very nice F-unit. Awesome video SMT! Keep up the great work!

That's the Southern Pacific "Black Widow" paint scheme - looks great. That being said...I would have cut the old end of that wire, stripped a new end lead, tinned it, and bent that into a hook to wrap around that screw. And WHERE can I get one of those carbon fiber pencils???? And in the end...SMT strikes again, with another fine job in rehabbing an old loco!!! Well done, sir, well done!!!

Wow such a cool locomotive

I'm amazed at how quiet that older style motor and transmission gearing are. Thanks for showing before and after running. It really makes it interesting to watch.

I would call those worm gears, Harrison. That locomotive sure has an interesting drive train. It's a smooth, quiet runner. Thanks for sharing. 👍 👍 👍

Very nice restoration! I remember you getting this loco a long while back and it’s nice to see it return!

Harrison great work

Nice locomotive Southern Pacific in HO scale, F- unit. Good job in the repair. Where is you 🐱 ? Scooby Doo is a good dog with the cats. Scooby Dum is a nice dog. Scrappy Doo my pup.

That's a sharp locomotive

great video liked 🚄👍

this made my crazy day

Southern pacific roll on roll on

That thing is incredibly quiet! Nice save.

MERRY CHRISTMAS Harrison and have s very Happy New Year!!!! 🌲🌲🌲🌲🎁🎁🎁🎁🧑‍🎄✝️🥳🎇🎆👍❤️📹😃

Smt after his acela flys off the table: it's a boy

Joining the Chesapeake bay and western train club and there strict all on the rolling stock you bring in so I’m spending my time getting my freight cars up to shape with there kadee couplers and good detail and wheels

Well done

I remmber when you got this a while ago

Ahh a brand ive Never heard of and a niceBlack widow paint scheme from 1950s. The wire on screw i would think a loop terminal connector would help so the screw is attached to loop not the wire creating fatigue maybe would help keep wire good. I like the tips about the motor which leads me to check mine one one of my locomotives because it had difficulty running. I think I have stuff on plates plus spring tension prob an issue. Good job Fixing her up

The limited stretch and eventual deterioration of that rubber tubing will put a bind on the trucks on the curves and more strain on the motor. Those drive trains are mechanically the best around IMO and will probably last forever with a bit of care. Your unit has the Pittman DC70 motor. A good unit. A more powerful motor, the Pittman DC90 can be found for that unit and will double the power, if not more.

And a last comment, see Spencer Tracy in "Bad Day at Black Rock" to see those Black Widow units is action back in the day when that paint scheme was new.

Good video

I have two of these. One is a match set A&B unit Union Pacific. I worked on them earlier today. Now they are running great. Had to do major cleaning inside getting old oil and grease, cleaning things up.

FYI...for the "pick" used for cleaning the commutator gaps? Try a dental flosser - you know, the kind that has a pic at the other end? That works pretty darned well.

why not repaint one of the F units in your extensive F unit collection into the nerf cat express' motive power!

Yay new SMT video! Very good looking unit and nice job restoring it!

If this oldie warrants the time spent on it, I would make up a fuel tank from plastic. It,again, is in need of some additional red to improve its appearance. There are lots of pictures to guide ya.

Hobby town had their own engines 😞I miss hobby town

SMT - As Swamphdaddy alluded to; you could use this engine to pull SP Daylight passenger cars - like the train in the movie, " Bad Day At Black Rock ". Some of the SP fans could verify if The Owl & other night trains were pulled by Black Widow diesels. The Kadee Conversion Chart in my Walther's catalog show #6 & #8 for Hobbytown diesels.

Nice locomotive and great restoration!! Keep it up!!:)

*subscribed*

Love the collection man can't wait to afford the hobby. Keep up the good work I've learned a few things since I've started watching

Can you make a video on how to wire ac switches on a DCC system

On that front truck...put some electrical tape on the inside of the frame, so it doesn't short on tight radius curves. Just an opinion.

I want to make a video of all the times you said well folks from the first video to right now lol

yes

I have a challenge for you SMT Can you hook up a freight train with the cars looping around the whole track and connecting to the other cupping

Thanks for telling me that you’re not from Switzerland because somebody replied to me that you were from Switzerland and I guess he’s wrong

I have a question for your digarax controller can you hook up a plug and play to it? I am looking to buy one.

Never heard of hobby town

When video starts I heard his saying a million times so when the vid started I said well folks and I’m today’s video…at the same time have smt

seem to be related to Hypoid gears - design found in automotive differentials

nice

Cool

Do you have substitute for the pencil and if so will that work on wheels too

If you want to do Multiple Unit diesel you should use HobbyTown engines because if you put a bigger motor in it. It should pull anything and if you do get one take it to a train club and do a traction test it’s funny what happens

I love SP

Will you be fixing it cosmetically?

Of course you can the train doctor can fix anything

i did a rebuilt on a hobby town southern pacific gp9 with in a month it was runing like new

Curious: where did you get the carbon fiber pencil from? It looks like a really good piece of kit for locomotive servicing. Oh, and if nobody mentioned it, I'm going to shamelessly shill for Micro-Mark. All the proper miniature tools you could ever want for maintaining your locomotives and rolling stock collection. But seriously, I bought several items like the "Truck Tuner", an NMRA track/wheel gauge, and a coupler height gauge. They've proved invaluable for keeping my equipment rolling and on track. I wouldn't recommend a tool site if I didn't actually use/approve of what they're offering. I guess that's enough word salad. Cheers! P.S. BTW, are you doing a Christmas Train challenge this year?

Very nice. Vintage? Ouch! Now put some horns on that thing.

What is that pen called ? Also what kind of oil for the gears do you you?

If anyone can help, What are some of the best reliable HO Steam locomotives with smoke?

Great video. Just to confirm a few things, YES hobbytown of Boston is still alive and No they're not sold in any stores, only online or at those now defunct things called train shows.! For those who never hear of them, they're the last of the original die cast locomotive kit manufacturers in the USA. They have been in business since 1946. They're now located in New Jersey. The shell is probably an old Athearn, hobbytown never made an F unit shell, and never made a plastic one either except for a few promotional and limited pieces.

Shredded cheese

Looks like an Athearn shell. Single headlight... maybe someone's upgrade from rubber band drive.

You need to get rid of the rubber tubing on drive shaft connecting the lower trucks, ditto same on motor to gear tower drive shaft. Hobbytown (one word) part #100000K which contains 2 brass drive shafts and universal couplings. Download their catalog at: hobbytownofboston.com/?page_id=53. A new owner is reissuing the old Hobbytown drives and metal bodies.

Everybody? 1...2...3... SHE'S A RUNNER!!!!

My name is Con Rail Man👍

This was a very good one. Thank you so much for taking the time to make this video. I had an engine designed like this and was completely stomped on how to get it running. Thanks to both you and this video, now I know what to do. Thanks again 😎

The next video is Cooking with smt mainline

I call it production complete but that’s amazing bud! I believe that engine shell looks kinda similar to the life like ones or probably bachmanns

Hi

Yes but yes no yes make scene

Scrump you really shouldnt mix oil with grease it liquifys the grease you dont want watery grease,,,,just a sugestion i have a repair shop for 45 years i have been repairing lionel and ho and never muxed oil and grease ,,,Ken

23rd person to comment as of now!!

I wish the Southern Pacific could unmerge with the Union Pacific

Hobby town as in the stores

I think it’s time to up your entertainment value. You should start fixing these locos underwater. Or blindfolded. Or blindfolded underwater with laser sharks circling you. Just an idea.

Why don’t you ever run train on the swiches

Guys I think he’s gotten so famous he doesn’t reply and love comments... NO NO NO NO NO NO NP RAILWAY SYSTEM lol

Hey buddy I got a deal for you I will send you two locos one in exchange you get my favorite loco running

You didn't say Serenity. LOL

What? No "Serenity!!" ?

No

First
