I have a Christmas set that I put in a Dept. village (engine, tender and two passenger cars). I saw a graduated pier set on Amazon that looked perfect for me to use in a village for a month or so. The reviews on Amazon are mixed on whether it can support the engine and cars and that getting the grade correctly can be problematic. Can someone comment on how to avoid slippage, etc. and go into some detail as to how to achieve the right spacing and gradient? One of the reviewers suggested two sets combined would be better.  I am less than a novice. When Bachmann came up with E-Z track, they were thinking of me. Thank you.
