No, you read it right! I have no idea what I was typing there...I think I misread a Google Search result and didn't click through the link. You are right that the number routes through to a regular LEGO train set, which is definitely NOT what I have on my hands. Indeed, the Alien Motor guys seem to have vaporized from this earth as with their namesake!. Their e-mail box is full so no joy there. Won't try to place an order with them, which is too bad, as they look like they had the solution! I think I will write next to the Hoi Po Motors group and see if they can help.

I was envisioning maybe two or three. :) I have found some hobby places that sell similar shaped motors with similar specifications, so I might just try a few of those to see if they work. They're literally a couple of bucks.

Thanks Robert. No, it's definitely DUPLO. This is the set it comes from: https://www.lego.com/en-ca/product/cargo-train-10875 One of the reasons I thought I'd post is that I didn't find anything on this particular problem, and thought I could add something to the literature, as it were. The curse of science training, I suppose. :) I will keep looking for a source for the motors. Maybe I'll hear something from the Alien Motor Company (how does anyone make this up!)

That's true. Looks like the whole motor set is about $40 CDN plus shipping off BrickLink. I did find a site online that looks to sell the motors: http://www.alienmotor.com/product_info.php?products_id=99 The website looks like it hasn't been updated since 2013 so I'm not sure it's still a going concern; I've written to them to find out. The motors on their own are about $5 USD, so a good bit cheaper. I'm also looking to do this partially for fun to see that I can fix the thing myself. I don't need the extra unit (got the fee replacement from LEGO) so the goal here is to avoid adding to a landfill when a few bucks for a hobby motor and ten minutes of soldering will create a backup engine. Looking on eBay there are more than a few of these engines that are broken and it would be nice to get them working again to create a DUPLO train fleet (why I'd need to do this who knows, but I like fixing stuff, so there you go). That said, I appreciate the quick replies!

Yes, the motors look the same. It looks like Hoi Po Motors is the manufacturer of the thing (how I missed that looking at it the first time around is anyone's guess!). The shape of the motor is identical to the two have on the left. Hopefully that means that these aren't too hard to find?

Hi everyone, I've got a one-year old LEGO DUPLO cargo train set (60198) that has a damaged motor. The part is HUB No.5, 28743. The good news is that LEGO was good enough to send me a new engine piece to replace it. However, after successfully taking the thing apart, a motor replacement seems a simple enough job. Desolder two leads, install a new motor, solder the leads, reassemble. The difficulty I am having is figuring out what motor to replace it with and where to find such a thing. A picture of the interior of the unit is attached. You can see the motor is labeled R 852H which doesn't seem to correspond with anything through Google that I can see. I'd welcome any suggestions as to potential sources of motor replacements or equally, to hear from anyone else who has tried repairing one of these. It seems like a big waste to just toss the thing, as the rest of it works and works so well. My kids certainly enjoy it!
