When I was kid my brother and I had an HO layout that our dad built for us. Every Christmas Santa would bring us each another car and more track, or switches and controls. Dad would tear the old layout up and, surprisingly enough, Santa always brought everything dad needed for the next layout.
We only had a couple buildings, and no scenery, just a four by eight table. The last layout was a figure eight in an oval, they shared one curve and the oval had a switching yard.
It was lots of fun, getting both trains running simultaneously and throwing the switches to keep them running at the same time.
I loved running the trains, it's building the layout that is the hard part. I don't think I have the devotion or patience.
Has anyone tried Microsoft's Train Simulator? I played it regularly for a while, then lost interest. It was fun seeing the controls, and learning the controls of a steam locomotive.
I think Camara has something, it's nice to just watch the model trains go around. I didn't get that with the train sim.
