Indeed--just because it's Bachmann does not mean it isn't a no-particular-scale toy. The plastic track and cheesy vacu-form Christmas-tree-base mountain are kind of a giveaway in that respect.
My wife has one almost just like yours. Our track is 1 1/8" also. this one has smoke and light with 5 cars and a sound train station. This one was made in China for ABC Distributing Inc., Miami, Fl.
yours looks much fancier than my parents' set, rcline
I'm planning to run a couple circles of old fashioned 3-rail O scale with a pair of Lionel Trains: a 1959 2-4-2 "scout" and 1946 4-6-2 "Dreyfus Hudson" Should be fun stuff!
