Did you see the initials? ES? That big boy belonged to Ed Sheeran! So cool. Speaking of initials, SMT now stands for So Much Talent. Great job!

I love that you film repairs on virtually every make and model, especially vintage ones. Watching these videos has been teaching me to repair mine

As soon as I see the "Can we make it run" in the title I already felt like yes it will and I hope it runs.

Nice job getting this one going.

Good thing you worked on that cabforward before, now you know how to deal with big engines

I love seeing your restoration videos; always great to see a Big Boy running again. Keep up the great work!

Super. The drive is a lot better than I imagined, and oiling the siderods, bearings, and valve gear is very important on a locomotive like this. I like the Big Boy, but will probably not buy one for my railroad, but if one just happens to come my way, I'd find an excuse to operate it on my railroads fantrips. 💙 T.E.N.

Love that there was a little 0-4-0 in there I love those little guys

First post: I thought I should let you know how much I enjoy your videos. Not only are the successes great, but your presentation is also very engaging. It just shows that old does not mean trash worthy. Much can be restored with patience and attention to detail.

I had a Riv Big Boy oh, so long ago. I enjoyed taking things apart and putting them back together. Fortunately I was intimidated by my steam locomotives and never attempted to disassemble any of them, because if I had, they never would have gone back together!

Excellent job on the repair someone will be a happy camper.

You probaly are unaware of this youtuber, but your like the Growling Sidewinder of HO scale train repairing, meaning every episode gets more amazing and you learn alot more than you think you knew

This man can make anything run

I just got myself a Rivarossi 4005 Big Boy that needed some new oil and grease. I got it from my local railroad club where it was running rough but with the help of your video here, I got her going smoothly! Hope you have a happy new year!

Another great fix and video. I am surprised you haven't run out of space in the basement

You taught me how to repair engines and that is now the way I buy most of my engines

He protec He attac But most importantly He knows what he’s doing in the back

Don’t know why the hell this was in my recommended but it was fun to watch

So cool!!! I love that layout.

yaaaay! another piece of model train history saved, i love it!

These things are so damn expensive, I wish I could get my hands on even a used one, or 3d print my own. Good find man.

Great work bringing it back from the scrap yard. Never doubted you could.

This would make a cool addition to my starter set up nice loco for sure

As a lover of old Rivarossi locos, thanks for the tender loving care. Lol. Always enjoyable watching you work your magic. See ya. Happy New Year.

Great job on the rebuild. This was a fun video to watch. This reminds of when I was a little boy and my Paternal Grandfather took me to the train yards of The Santa Fe Railroad. Seeing anything train related reminds me of my childhood days. Thanks for showing this particular video

Am I the only one that is actually happy for the trains that he fixes?

Looks like you took a tip from Ron form classic model trains on that wheel cleaning technique. Those wheels look SO clean... Thanks, enjoyed the video...

I remember when you were at 5k subscribers... Man have you grown. The quality of the videos you produce always increases. I can really see your channel being a well known name in model railroading, but that's in the future. It's a long way to get there, but you will.

I used to use a small brass wire brush to clean wheels. I attached a wire between it and a 9v battery and had a return wire to complete the circuit so the brush itself powered the loco whilst cleaning the wheels.

I’m blown away that you took that Big Boy apart (which I could do) but then cleaned it, got it running, and most importantly, put it back together with no leftover parts. (Which I could not do, lol.) A+ to you.

I've had a few of Rivarossi's articulated locomotives. I've never been game to disassemble the drivetrain quite as far as you did. But I think I'll be able to give it a go on the next one I get thanks to seeing this!

man, discovered your channel yesterday. You have got this KZfaq thing nailed. Great vid work, great lighting, perfect narrative, fun storylines, for us model train guys and gals to enjoy. Love your "rehab mechanicals" videos the best but the Train Store archeology tours are very cool. Spent many hours in them across the US collecting in my travels. So thank you, and your friends for saving the old stuff we had as a kid and then an adult. Had to part with my collections several times, (space, no basement.) Great to see some Gen Zs enjoying this hobby.

You are a very talented young man..great work and care

another great video. You inspire me to try and repair my locomotives and to be sure , all of us are in awe of your ability. Keep up the good work, we all look forward to your videos

Oh jeez, I need this. My Rivarossi mallet blew itself up and I would love to have another beast on the rails once again until I fix mine… I will get this loco until I can’t… then I’ll be sad. Also that speed up edit at the end was hilarious and it jump scared me 😂

Its always so interesting to watch the intricate breakdown of these bigger engines. I personally like my N scales as it feels a bit easier for me with less parts!

Great demonstration. I will use these techniques on my own Big Boy that needs repair. Thank you for posting another valuable video.

These videos are always so satisfying. Glad this ran!

I love the big boy! It's really cool looking.

Another great job Harrison!!!

Toys for tots is a great charity. An incredible idea. This is a beautiful locomotive. It was great watching you fix and service this locomotive. The Harrison Touch again prevails. I know it has been some Time since this aired but I explained in your latest video as to why. Thank you so much for sharing this video. 💕❤💕 I hope you raise a lot of money for what you choose for the charity.

Nicely done Harrison!

My 6 year old loves trains. We got to see the big boy when it came through eastern Oklahoma.

I've been watching your video's for well over a year now and I've noticed that you have become very good at Model Locomotive diagnosis and repair. Keep up the good work. I look forward to all of your video's.

You do a great job on repairs. You leave no stone unturned. I'm watching your channel from New Zealand.

Thank you Harrison for the excellent restoration of the Rivarossi Big Boy (aka..beast). And thank you especially for the track side running shots of this monster in real time and slow motion. Happy New Year to you and yours!! :-)

excellent video. I have one of these engines, in fact 4005 like yours. Once clean and lubricated can pull 40 cars on level track. Love these large articulateds

Great job on the repair, runs beautifully Harrison!

That's really cool that you got this locomotive running. The tender looks like it goes to a Riverrossi mallet locomotive my uncle used to have one. My current uncle has it and you won't let it go for anything maybe I'll buy it off of him who knows but they claim that there's no parts available which I heard the same thing from a hobby store. I'm glad that you are careful taking apart this locomotive because the availability of parts I bet is slim. Everything you do in these videos I do to my locomotives that's why they run so good. I loved the run bys that you did.

Good job on fixing the Bigboy Man 🎉

Have a happy New Year . Great job again.

Good job. Very interesting to watch how you repaired it.

It is incredible to see the process of how to repair a Rivarossi Big Boy, plus it reminded me that if one day I have one of those locomotives, I would like to customize it so that it looks like the BIG ONE, is from the anime "The Galaxy Railways", greetings and good video!

So great! It's very interesting seeing the guts on that kind of locomotives. The engineering work done to do them run is amazing. And Rivarossi always surprise with such small motors. Great video!

Sadly I don’t have the space anymore for this hobby. I have other expensive hobbies anyways. Love the repair. Loved the video though. 👌🏻

Fantastic Video as Always SMT

Love watching your can we make it run videos. They're really enjoyable and relaxing to watch.

You did a great job! 👍😎

good job to make it run that way. Happy New Year Harisson

What a nice rig. Always have been a fan of the big boys, even as a child! Let alone model trains in general!

That big boy looks amazing goin around ur track

This was such an impressive fix.

nice job and nice piece in youre collection !

I feel a lot more confident servicing a big boy after your video, well done from across the pond, regards pete

Loving the camera work on this video keep up the good work

A one of a kind toy you really out done yourself here great job

nice job on that one iv got a couple older Rivarossi big boy locos in N they run well if you keep up the maintenance on them

Darned fine runner there! I was rather surprised the motor was in as good of a condition as it is! Another fantastic Dr. SMT surgery - ya brought her back to perfect health!!! Now..if you could only convert her to DCC and a sound decoder....

Hello! You are the best locomotive doctor!👍

What a great locomotive, came across your channel randomly, glad I did. Great content. subbed

Great video! Loved seeing and hearing the engine run and pull a train!

You rescued a mammoth (for that you deserved all the holy respects)

Love hearing Well folks!

Great job! I wish you happy new year...

My mom found me a limited edition HO scale Publix Express train set by International Hobby Corporation for Christmas. I work for Publix in the state of florida and it’s a grocery store chain. For 25 consecutive years, the company has been recognized by Fortune as a great place to work

Well done and nice to see someone open them up. We used to look at 4014 and wonder if it was just going to rot

I want to get a big boy for my layout ! I love these gorgeous machines ..me and my pop pop chased one from saint peters mo to pacific missouri ... amazing beast ... every time I see one it reminds me of him!

Nice job. It's a beautiful engine. I'm surprised it wasn't dirtier.

Good job. Really nice engine. Just needed a little cleaning and maintenance.

Excellent as always, thanks for the video Harrison😀👍 I'm resurrecting a RivaRossi Cab Forward. She has significant Zinc Pest, I'm going to slather a layer of JB weld all over that😁 Motors good, drive train too. Got lucky and found her at an estate sale for $60 USD I've got screenshots of your Cab Forward Video for reference. Thanks alot, take care.

Wow man! I bet you got another big boy for fun but I’m glad you got this thing running here and pretty cool that your giving it away as a raffle.

Nice old Rivarossi - that's a model I always wanted as a kid. I'd have cleaned the wheels and checked the wheel pickup brushes before I did anything else with an old engine like that - most of the time that's the only problem.

Bit of history on 4005, it was the only Big Boy to wreck. It was later repaired, then retired and placed on display in Cheyenne, Wyoming. I've actually visited it before, and it's in pretty rough shape. Great video like always Harrison! Keep it up.

One of my favorite locomotive

that looks great nice job

This is amazing. Im currently looking for a big boy for my layout. I love big steam locos. Ive seen the big boy in person and it was amazing. Really a beautiful sight to behold

I want a Rivarossi Big Boy!

Good looking locomotive

great work!

great work harrison,nice one,happy new year.jpj

Terrific work! Beautiful collection. Subscribed.

Looks great. Fun video to watch

Love your videos!

Love your content, keep making more vids please

Look at you Harrison. Big Boy engine detective. Great video as always.

I had one kinda like that one, but now a member of my family has the train set, the more I watch your videos I am getting the bug again hoping to maybe find a small train set for the Christmas tree this year.

Heres a trick for you- try dunking a problematic motor in water and running it. I race radio control cars and back in the day that was a great way to clean the coms brushes, or break them in for new motors without lots of deposits on the comm. You can use tap water, just use motor spray (brake cleaner) to clean it out. BUT with your motors I'd use distilled water. Either way direct current motors will run just fine underwater. Theres lots of youtube videos showing this. And there are still brush and comm cleaning tools sold on (bigger) rc rock crawling websites as a lot of them still used brushed motors. Just something to try! Obviously thoroughly clean the motor out after with something thats paint safe but should work well for you!

If you believe "Toy Story, I would say this guy looks like he's happy to be running again. 😂

Awesome job

You look to have a great layout.
