I'm new to LEGO and am trying to motorize my Hogwarts Express train. Per the LEGO site, I bought the 88011 Train Motor and the 88006 Move Hub. But I can't figure out how to use them. I connected the wire from the Train Motor to the C and D ports but get nothing.

I downloaded the Powered Up App (which I also don't understand) which was synced with the Move Hub so at least I know the Hub batteries were installed correctly. Within the app I created a project ("Train") but then what? Are there instructions that explain the icons in the app and how to use them?

I also have a controller from a City Passenger Train (which does run) but I don't see how to use it with the 88011 Train Motor. The controller seems to control ports A and B but ports A and B on the Move Hub look like red axles.

I've tried YouTube but the YouTube videos don't bother explaining these basics as if to say "If you have to ask, you're probably too dumb to use LEGOs."

So, can someone please help me get to first base by getting this train motor to do something? What do I plug the Train Motor cable into? And then, how do I say "GO"?

Thanks in advance.
