For me I had Marx trains as a boy. Then as I got older, my dad bought some Marx ho trains and true scale road bed and rails. We set up a 4x8 and started to build a layout. My dad didn't understand electricity, and everything worked until we put in two switches with a crossing track and had two reverse loops with no insulators. We never figured out why it didn't run. I realised it in hindsight after I got interrested in trains as an adult. After I got married, my wife and I had two daughters. Needless to say, we spent a lot of time at ToysRus, but of course we were always looking at dolls and such. One day while at ToysRus, I told my wife I was going to look at "guy stuff." I ended up bringing home the ho "John Bull" train from Bachmann. It doesn't run very well, but I have it packed with the Christmas decorations and we set it up with a few pieces of track as a static display with my wife's Christmas Village stuff. I bought a set of Roundhouse Overton shorty passenger cars and a Rivarossi 4-4-0 V&T Genoa. One of these years, I'm going to build a small layout incorporating my wife's Christmas Village and perhaps a bit of animation.
