I've not been in the hobby anywhere near as long as some around here, but my dad was a train driver, and he bought me my first train set in 1972.
I haven't always been an avid modeller, and most of that time, had no layout, but I have bought at least engine or other every year since then, when something caught my eye.
My 7800 is, by far, the best steam engine I have ever purchased, and I include my fully diecast Broadway Limited Big Boy in that.
