Hi there,
I've been reading this forum now for some time, and found a lot of interesting topics/ideas flowing by, so I'd like to participate a bit more. I'm Ron, 39 years old, from Eindhoven in the Netherlands. I've been enjoying when I was a little boy, and recently rediscovered it when I bought my Son the 7939 train set. I've always enjoying playing with the lego trains a lot, having a 720 and 7760 on a 12V track (blue) when I was young.
When we set up the 7939 on the attic with the rest of his lego, I decided it was time to revive my old trains as well, which is what got my heavily back into lego. I've since then converted both the 720 and 7760 to use power functions (with the original 12V motors), and treated myself on a double Horizon Express on new year.
I've also discovered bricklink, which really opens up opportunities. It's the thing I missed when I was a little kid (well, internet didn't exist back then either ;-) )
