Zephyr that looks great! Do you have specifics/schematics on your switching apparatus? I looked at your link, but could not find any (or I'm just blind, which is possible). I see medium motors, and a little box. What's in the box? :)
Arduino could be interesting, but I'm hoping for a lazier route. Oooooh the PF switches are a great idea. It will take me back to my HO days. Thank you all so much!
I find it both fascinating and infuriating that Lego made a set that all of us are going to "have" to buy two of. I mean, I have to have two. There's no question. Sooo pretty. And it seems like everyone else here will, as well. Just makes me "ugh" and yet "squee" at the same time.
Spitfire2865 - That's a good idea. Thanks for the link too! I will have to do that.
legoboy3998 - I'm hoping to be able to run four or five engines at a time, or at least be able to without having to turn things off or on. So that only leaves me four or three slots, and I have more switches than that. The distance thing is definitely a good idea though. I may have to test that theory (since that won't require much effort :)). Thanks!
So I will soon have 4 trains (some with lights), and I have a bunch of track switches. I wanted to mechanize the switches, but I will quickly run out of spaces on my Power Functions channels. Does anyone have any ideas on how to mod a set of Power Functions remotes and IR Receivers to be on four totally new channels?
