Woah... looks simple from the outside but VERY nicely done with the complex internal structure.

You guys said it all. Amazing models, it's great that the 12v and 4.5v era is still alive today.

Oh, and the 12v trains actually run at about 16 volts maximum... so you may want to factor that in. 12 volts will give a decent clip but won't be the max speed. I personally don't usually run my trains at max speed because I'd prefer to preserve the contacts for as long as possible.

The stiff controller might be able to be fixed by just continuing to move/turn it, I also got a 7864 recently and the dial was a bit stiff when I received it, but after using it for a couple of weeks it's smooth and easy to turn. I think if the track connection wire isn't having any problems with conducting, you should be fine, I agree that there probably isn't much you can do without opening the casing. Worst comes to worst you can buy a used 7864 or even just the transformer part for $5-10 on BL. Shipping isn't cheap (trust me, I know... running 12v trains in the US isn't easy...) but you can probably get away with it for under $50. Welcome to Eurobricks, and like you, I also run 12v trains in the US. The 7740 isn't cheap... hold onto it! I'm glad the 12v gray era is still alive today. Also, I don't know if you've done any research on voltage converters. But if you haven't, here's the one I purchased and it works great: https://www.amazon.com/PowerBright-Transformer-Countries-Convert-220-240/dp/B000MW83OG/ref=sr_1_3? Good luck!

Hmm, interesting. I also am running a Christmas train with PF right now, not sure if I want to invest in the 9v system yet. The 4561 doesn't look like a bad option for someone just looking to have an oval loop.

Ooh... looks like an interesting project, will have to look into it! Thank you so much Lok!

Wow! I really like the design of the driveshaft, it's interesting that it uses a worm drive. I would expect a worm drive to go pretty slowly but since you geared up the motor it looks to go at a pretty decent clip. I would definitely tinker with one of these, but alas, I don't have any narrow-gauge tracks. I do own 12v track but the radius of the curves isn't the same.

Thank you!

Thanks Pdaitabird, will have to look into that. Seems pretty simple to make and as you said, reversing mistakes could be invaluable.

Ooh super cool... I might have to get an 890 just to try something like this!

Like with a hot glue gun? Yeah, I thought that also might work. I do have a hot glue gun so that might work.

Thanks! Will I be able to reopen the motor if need be?

I may have to open a 12v train motor soon (2nd generation), due to the fact that one of the contacts is wearing out. I've read Andromeda's post about opening the motor and am going to get a 1151 to take apart for contacts, and also have read a lot about the internals of the motor. I am planning to make a jig to hold the motor, and use a BIC single razor blade (as someone else did, I think it was Andromeda) to break the seal of glue around the bottom. I know what is inside the motor and am also planning to clean everything out, and replace the contacts and re-grease the axles. However, I am unclear on what type of grease I should use to re-lubricate the axles, as well as what type of glue is good for resealing the motor. I have read that if you use the wrong type of glue then it will be very hard to open up again if need be. Does anyone have any pointers on what types of grease and glue to buy, or any tips for opening and cleaning the motor? Thank you so much! And, on a side note: I know the 3rd generation of 12v motors is apparently very hard to get open. Does anyone know why that is, and/or how to get it open? Not planning to open that type up anytime soon but the information could be useful in the future for me and the community.

Ooh, very nice! I made a steam locomotive a month or 2 ago that looked similar to the first model, it was powered by a PF L motor. I also like the 2nd and 3rd models, the colors on the diesel are unique but I like the combination, and the boiler on the 2nd model looks pretty clean.

Yes! I was lucky enough to get a 10219 when it released, and am now very happy about it considering the price on the secondary market... recently resurrected it from my collection!

Hi Eurobricks train fans, I'm relatively new to the 12v community (and to Eurobricks), but have done extensive research on MANY aspects of it. I bought a 7745 off of Bricklink, thankfully it had all of the stickers. Sadly as I live in the US, shipping is expensive and I had to buy a voltage converter from Amazon, but everything is working OK right now. I'm planning on ordering a 7858, a 7859, and 2x 7860 for the holidays and some more stuff, such as wires and extra lights to light up the station. Anyone have any tips about the system? Also, my only motor that I have, the contacts on the bottom are starting to wear out. I am going to order a 1151 off of Bricklink so I can break those open and open the motor to replace the contacts and clean the motor if it gets bad. Currently I have 24 curves, 24 straights, and 1 cross track, which is a decent amount of track for starters. I am planning on expanding this layout/setup long-term, hopefully in a couple of months I might actually be able to buy a nice condition 7740! I'm excited to follow the 12v road wherever it may take me, and I am definitely invested in this long-term. Just post anything about the system, from favorite trains to maintenance tips. I appreciate it!

Wow Andy, that's really helpful! What's the voltage limit on the M-motor? Also, I only have a PF L motor as my M-motor broke. :( But I think the L motor also fits inside the Crocodile body.

Those are beautiful! I wish I had the parts to build one, but alas, shipping is EXPENSIVE to the US and I have almost none of the parts there... Maybe someday!

Very very nice! Love the high-quality photos on the small 12v layout. I'm hopefully going to order 2 electric points and 2 signals tomorrow! Love the design, it looks pretty compact and I love that you were able to fit a light brick in the front. I don't own one of the red motors (yet...) but I can definitely appreciate the rarity and aesthetics. Also, that 7777 loco in the back looks awesome!

Cool! Yeah, a lot of people are also modifying the 2 end sections to cover the gaps between them and the center section. Is it motorized? I'm thinking of buying one for the holidays, thoughts on the set?

What do you guys think of the new Crocodile? I'm mainly investing in the 12v system right now, but trying to decide if I should shell out for a Crocodile. They're not cheap and if I buy the croc I might want to buy the PuP to motorize it, but I do really like the design. Thoughts? I own some of the PF/RC trains (7898, 7938, 3677, Maersk) and also a 7745, so I have PF and 12v track. Or, should I save up for a 7740 :)

Wow! Does it beat the Millennium Falcon for piece count?

Very cool! Awesome shape in a small body!

Dang, very clean and great functionality!

Watched this on YT, completely awesome layout! I just started getting invested in 12v, currently I have a 7745 but the motor is starting to wear. Planning on ordering 2 electric points and 2 signals for the holidays!
