Sal,
The 072 switches for the main line are good, remember if you use 036 for your yard and sidings there are some big engines you will not be able run thru them, its one of the reasons I use 048's for my sidings. Also you want to know about certain track pieces, I recommend you look into purchasing a Rockwell X2 portable table saw for making custom FasTrack pieces at any length and radius you may need for planning your new layout. These new X2 saws are just incredible for making FasTrack custom pieces.

Great, very light portable table saw, and the over head in the 2nd picture is completely removable while working/cutting custom FT pieces. It's an under table mounted Jig Saw, that works at high speed and at any angle you need for making custom FasTrack pieces for building your layout. No more looking for exacting FasTrack pieces, you simply cut your own with the BladeRunner X2
