I was into model railroading for a number of years. It started with a Lionel set. My father bought the trains for me back in the very early 1950's. They included a 686 Steam Turbine and tender, 8 cars, and caboose. A number of building, a stock yard, a logging facility, and much more.
When I was about 12 years old, I switched from "O" gauge ( Lionel "027) to HO.
Presently a lot of steam and diesels, and three GE-GG1's.
Have a small collection of "N" gauge. Mostly diesel engines, an two F9 A/A set the ATSF "war bonnet" paint scheme, and a few various GP units. O have one "N{ steam engine, it's a 2-6-2 with tender. It was a set that came with 4 passenger coaches and a baggage car. About 12 pieces of freight rolling stock.
