It's a hobby you can take as far as you want to; everything from the simple circle-around-the-tree at Christmas to warehouse-sized, meticulously-detailed layouts that look like the real thing shrunk down.
I've seen numerous photos of models where it was nearly impossible to tell that you weren't looking at a photo of the real deal.
If I were going to set up a train garden, I would choose a scale where I could conceal a video camera in the locomotive.
I'd also like to arrange for some remote control cars, in a controlled (garden-like) environment, where you could see through a video camera what the car's windshield would reveal.
That could make some fun out of competitive racing games.
