This is the second route I have built were I found some sections of the "Fixed Track" does not line up with the gauge of the Auran 2009 oak track gauge. The gauge on the fixed track is slightly wider. It's hard to tell when laying track. It all looks O.K. but trains will derail when you try to run. Anyone else have this problem? How do you fix it? Last time I had to tear out all the fixed track. Deisan
