track plan

If you just want the cloverleaf pattern in "O", you need 4 crossings, 24 O-31 Curves, & 16 10" Straights. No fitters or cutting.

Bill,

Hwew'a a simple cloverleaf in O31.  It does not have the outside loop.  No cutting necessary.

Perfect thank you.  What size  radius would go around it O36 ?

I might do it this way.  Not my best sketching, just something I did while reading this thread.

Thanks Dan

i am going to elavate the clover leaf and run a second track around the  perimeter  that will have cup cakes on flat cars.  Not sure yet what would be the best  radius

It's 66" x 66", so you could do a circle of O-72 or a square/rectangle of O-36, O-42, O-48, or O-54 with the requisite or desired straight sections on the sides.

Rob ,  when straight  pieces  would be needed for O36  corners in a  rectangle pattern just outside the  elevated cloverleaf 

Bill,

I added the outside loop.  If you don't use the crossovers you can use different elevations between the cloverleaf and the outside loop.  All the curve are O31.

There are two custom cut straights on the two cloverleaf crossovers.  The outside loop has three on the left side.

Are you thinking of using FasTrak?

Hi Jan,  the clover leaf is an elevated loop with no connection with lower level outside loop.  What  radius did you use for the lower level outside loop ?

Sorry Jan I just noticed you used all O31

I used O31 like you said in the original post.

Traditional tubular

If you use FasTrack, three straights per side will give you 70" x 70" outside dimensions, you would need all 66" x 66" to clear the inner elevated supports.

For tubular w/o the roadbed, it won't be as tight on the inside, and will be less than 70" x 70" overall.
