If you know boys, you know they like trains. We initially found a used train table on craigslist cheap, which we purchased for their 3rd birthday. (Their 4th birthday is right around the corner!) Luckily, it included the original instructions for set-up, so we had a guide on how to set up the tracks. After a year of the boys taking the tracks apart, we eventually figured out how to put it back together from memory. We then acquired another train table, and extra tracks from a family member. Just in time too, ours was falling apart. We moved it upstairs and downstairs too many times. So we get the new table in the house, and stare at it puzzlingly. It's smaller than the last one, which means it doesn't support the last set-up. But now, we have approximately 2 1/2 tables worth of tracks, bridges, etc. Time to get creative! This is what I came up with.
I also had enough extra tracks that I set up more on their floor. It spanned half of their room, and was pretty basic. It was taken apart almost immediately, and I never got a picture to show just how many tracks we have now. They use up both drawers, and store larger pieces underneath. We have 2 turn tables, a round house, and a big bridge just to mention a few.
