You will love s gauge. I use Gilbert track and switches which work for both american flyer and american models cars and engines. BUT If I were just starting a new layout I would use one of the other manufacturers for track ......note....I have a lionel american flyer big boy that has had it trucks and tender centipede wheels narrowed for sale if you are interested.......I am a N&W and Clinchfield fan and I no longer have room for western roads on my layout. I like American Models cars very much////// good detail and run very well. Lots of road names ,,,,,,,, Menards make O gauge buildings That are really neat and will work well gilberts buildings .
