I use rechargeable AAA batteries. The NiCD batteries seem to do ok, but I know many use lithium batteries for their higher voltage and perhaps longer runtime. KeyBrick One is also an option but they are very expensive and often out of stock, I have a few friends that swear by them.

Much appreciated, will look into it!!

Thanks! The information was added at some point on their website, It's still kind of a pain to find. Why this information wasn't in the manuals that came with the set I'll never understand. I have an updated tutorial for PU that goes a little more in depth if you ever have any more issues, it's linked in the description. If you have any issues that aren't covered I'd like to hear about them.

@@BatteryPoweredBricks hey I tried connecting today and my remote always turns off on the second train. I am really at a loss here.

definitely check out the updated video, about 3 minutes and 30 seconds in shows the updated procedure kzfaq.info/get/bejne/e92ihNhlrrfMZmw.html

Yes, pretty much the same as what's shown in the video but make sure both motors are plugged into port A and they will be controlled together

Thanks! Some of the info in this video is incorrect / outdated. I'll link my newer video, I've debated on deleting this video but it still gets views so I'm between a rock and a hard place. I don't know if it was added after the fact or not, but LEGO does have instructions for pairing multiple hubs now. At this point I don't expect LEGO to do any better for the train community, they are focused on their target audience, which is not AFOLs. The Train theme (or now just a party of City) has been going downhill for decades. The 12v line was peak for train enthusiasts. Here's the more recent video with updated information kzfaq.info/get/bejne/e92ihNhlrrfMZmw.html

In this case I physically turned the motor around and ran the cable through the back. Now I'm using PyBricks (an alternative to the official Lego firmware) and a program modified by one of our discord members to allow for controlling multiple trains and having full control of the direction of each of the motors

Yep, that's an option as well!

No problem! I have an updated video that shows a better method and goes into a bit more detail. I couldn't believe how long it took me to find out how to do this 😅

No problem! I have an updated video with a better procedure and a bit more detail. I don't know if it was added later or if it was just that hard to find, but Lego has the instructions on their site now 😅

@@BatteryPoweredBricks just watched your PyBricks video as well, reversing the motor direction, a slow precise mode you can turn on and off, hold to slowly accelerate, program gentle acceleration to set speed setting, run two motors off the one hub from one switch, with one in reverse. THIS IS INCREDIBLE. wondering if it would let me control one Train per side of the remote, both with two hubs, (on hub on each end of a passenger train) and both ends of each train having two motors, half of all motors running in reverse. I will be playing with this as soon as I tidy up and reorganise the lego room/city - so in another few months haha. Thank you so much, you're the best resource for lego train powered up set up and modification that I've found . By far!

Thanks! I got back into Lego trains last year and it took me quite a lot of research to learn all I did. I prefer concise tutorials with voice over and didn't really see any I liked, so I made my own 😅. With PyBricks I don't think there is a way to connect multiple hubs to a single remote. They are constantly working on new things so this may change. Another option is using the Brick Automation Project software and you can control many trains with sliders on a PC. I have a video on that as well 😁. If you have any questions don't hesitate to reach out, I don't think of it as work or tech support, more like potential video ideas 😀. Play well!

That's an option too, which I've mentioned in other videos. But when performing shunting maneuvers with several trains a single button per train makes it a lot easier

I mostly stick to buying used Lego, but will still buy new products if they meet my standards / budget. If it wasn't for third party firmware / software such as Pybricks for the new Powered Up devices I may not have bought in at all. Official apps will only be around so long before being abandoned. For me Lego isn't about the company, it's an idea, it's a community, Whatever bad decisions the Lego company makes will never change that for me

I have an updated video that shows it a bit more clearly. When connecting the second hub, press the button on the hub and the light will start blinking. Then press and hold the button on the second hub and the controller for a couple seconds, it should connect right up. If you still have issues you can connect the hubs to a phone with the Powered Up app and make sure it has the latest firmware.

​@@BatteryPoweredBricks Thanks for the reply. I tried your way many times and it didn't work. However, the good news is I finally managed to connect two trains to the same controller. After I had paired the first train with remote controller I paired the second train (that is hub inside of it) with... the first train (simply by pressing green buttons for a moment on both trains at the same time for a second). Now it works - I can control both trains with the same remote controller. Every time I turn on the trains I repeat the procedure.

That's strange. Once I get them connected I've never had to repeat the procedure unless I reset them 🤔

Up to 5 per controller. I made an updated tutorial that shows a better method to connect them and it has a few other details such as using multiple channels on a remote. kzfaq.info/get/bejne/e92ihNhlrrfMZmw.html

Can I connect my 60197 x 2 60336, 60198 and hogwarts express to one remote? ​@@BatteryPoweredBricks

I don't remember if I mentioned it in the video but for the locomotive you want to be on the B side, make sure the motor is plugged into the B port on the hub

I have an updated video that is a bit better. I pretty much use PyBricks exclusively now. One of our discord members has been updating a script from a Eurobricks user and adding several features. He's currently working on multiple trains on one controller. But it already allows for smooth acceleration, lights, tying multiple locomotives together and much more. I wasn't really a fan of BT for trains until I started using PyBricks and the Brick Automation Project software. I never really liked Power Functions IR control, plenty of problems there as well

@@BatteryPoweredBricks I tried to follow the LEGO instructions for connecting two different hubs to one controller but their instructions are clear as mud and I couldn’t get it to work. There was some other instruction for something else which said to wait for the purple light. I’d see a blue light but not a purple one so thought I was doing something wrong until I realised the blue light was purple (even my housemate described it as blueish-lavender, and not really purple). Generally I find implementation of Bluetooth by most companies to be half-baked and convoluted, and LEGO is certainly no exception. I have a day off work today for Anzac Day so will read up on PyBricks. It’s been some years since I last did some coding but text based is definitely preferable to obscure esoteric icons which are almost indistinguishable from each other on a phone screen.

We all use the same script for our trains. It automatically determines the type of motor etc. You just have to set the direction they need to turn. I made a tutorial at the end of last year that should be mostly up to date. Also if you are a discord user you can join us there for the latest updates / exploits. They are much better coders than me 😅
