I have 4 year old boys and currently have the basic lionel metal track
0-27 with a basic starter set train. Thinking about switching over to one of the newer track systems. They layout will either be on wooden floor or carpet. I plan to go to a local train store and have only researched on-line - but thinking of either the lionel fastrack or realtrax. The layout will be changed often and picked up often as well- so easy ability to disconect and reconect pieces is a plus.
Can't tell from my reading here if there is a clear cut winner of fastrack or realtrax.
