When I was a child, my favourite toy (maybe the only toy I played with) was LEGO. My favourite themes were Town and 12V Train.
Like almost every AFOL, I had my "dark ages" during the high school and the first years of university. But, one year, when I was ill and was forced to stay at home, I had the idea to build some of my old favourite LEGO sets. I started with some town sets, then with some custom cars and buildings... and when I had enough space on a table I built a 12V railway track with a passenger station.
As an AFOL, I began to take photos of my creations (unfortunately I didn't take any photos of my town layouts when I was a child!). You can find them here and on my Brickshelf gallery.
