1) Right, I have also looked for add on green lighted track but haven't found any yet. I did see a post the other day where somebody found extra green track being sold as part of a set break up. Will be interesting to see if add on track is offered in the 2021 catalog.
2) I have the Area 51 Set and definitely plan on using a transformer once I get this set up off the floor and build a small layout. I'm guessing it's OK to use AC. In fact, I think there have been a few posts of Christmas layouts with lighted FasTrak where a transformer was used in place of the wall wart.
Edit: Forgot to mention that it looks like Gryzboski's Trains is selling Area 51 as a set break up on the auction site. I see the trains but not the track. Could be worth a call.
