Sal,
Your FT track design looks real good, however I think you are making a mistake with 036 FT switches, IMO 060's are much better and if you have the space the 072 better yet. I use nothing smaller than the 048's and they are for sidings. All my different trains run perfectly engineering in this manner, even my original Tin Plate, with all the big rolling stock. Also if you are going to get into Legacy purchase the FT Command Control Switches, that are controlled from your Cab2 or Cab1 remotes. IMO 036 switches are to tight for all the different engines and rolling stock, my advise is to use
at least 060 or bigger on your main line and 048's for your sidings.
