Reply to "036 Fastrak vs 042 Tube Track"

Jeff, how close to O42 can you go? Here is a O41 Fastrack compound curve that will likely run a lot of O42. Add in the width of FasTrack 3.5" wide roadbed, and you need 44.5" of width for the O41 compound. (red sections are O36 quarter, gray sections are O48). Its not perfectly regular as a circle, but close. Lots of small sections runs the cost up some.

Right curve is slightly narrower, but less "perfect" IMO.

The left curve has O48 lead-ins, giving you O48 easements in effect.
