Best way to do this, IMHO:
- download the RTS software from Atlas (free)
- start with a large table in RTS, say 4ft x 8ft
- draw the layout up in RTS using the N code 55 track library. Pick your radius to suit. Make any changes you want at the same time.
- measure the outside dimensions of your track plan and add 4" to both the width and length. You now have the new dimensions with the larger radius track.
my thoughts, your choices
