Was a big fan of MTH Trains (O scale) when they came out. Use to put a display up for the holidays that was roughly 22x5 with 4 trains running. Used the RealTrax since we took it down after the holidays. Over time the track tabs would break but I purchased so much of it I was good till few years ago I had to buy some more. Quality has changed as the rails on the track I had were solid and the crap MTH sells today is more like the old Lionel track. It's more stamped tin track and hollow inside. Best thing about is ... the new track wont work with the older, especially the curves, as the rails don't line up.
