Thanks, glad to know you like it! :)

Yeah, I've had to do that a few times until I'd collected enough DC ones. I've found that sometimes for audio applications you still have to add more filters even to a DC supply. But that's a bit beyond a basic intro... :)TS

Hi, sorry it took me a while to get back to you. That should be possible, you could use a microswitch with a cover on it so it looks like scenery or more practically you could use an LDR to activate a relay that turns the lights on when the train is over it. There are loads of good instructables on wiring those up, but feel free to message me if you want to know more :)TS

Hi, sorry it's taken me a while to read this, but I'm glad you like the project! I don't really know how you would make a miniature jet engine, though that would be really cool! But doing a 2 engine plane shouldn't be too difficult, you just need another motor in parallel with the first one, everything else can be the same. Hope it goes well, be sure to share the results! :)TS
