Hi all, new guy here. I am working on my first layout, which will be a point-to-point railway going around the high balcony/shelf area that encompasses much of our home's Great Room. I have purchased a Lionel Village Trolley set and the Lionel Polar Express Set. I realize the track types are not compatible; I am planning on keeping the Fastrack for a possible Christmas loop next year. I intended to use the type of track that comes with the trolley to construct one main railway, because it will be less expensive to purchase additional track. Which brings me to my question: Does anyone know exactly what type of track comes with the Trolley set? It is #21969. The product description reads "O-27 Gauge". Does that mean that I can just go ahead and buy some additional O-27 track and it will work with the track that comes with the set? I had been wondering for some time what to do with all the space in that balcony area, and when the idea of "train" came to me, it just clicked. So I have been really excited about getting it all going.....I feel like a little kid again as I imagine all of the little stops I will be constructing along the route. Mountains, dinosaurs, Star Wars action figures, Dept. 56 villages--nothing is out of bounds for this layout! I can tell this is going to be pretty addicting, I just hope my pocketbook (and schedule) can handle the shock!
