My 3 year old is train obsessed too My first post good forum We are from Sydney as well. Nice to know that We are not the only ones with a train obsessed lad. Our boy is 3.5 and almost from day 1 has had a thing for trains. Do you know about "the train shed" at Luddenham? They have a Thomas ride on train plus a few trainsets. (for the adults there is a winery there too). I have managed to get my 6.5 year old daughter interested too. We are looking at building a zigzag lay out in HO. So we are in the planning process. We went to the Epping model train show on the weekend and the kids had a great time looking at the diffrent layouts to get ideas. The lad loves his thomas Blue track & likes putting diffrent layouts up. This week he learned how to set the points to make the train take diffrent tracks. Lots of good ideas on the net for layouts.
