I have some EZ Track turnouts with problem internal switch machines.  Has anyone used twin-coil (Atlas) or motor (Tortoise) switch machines on EZ Track remote turnouts?

I would like to aplogize for not having thought out my original post.  I came close to answering my question myself in the second sentence of my reply (Reply #2). In my current layout I took liberties with the slight flex at the track to track connections this resulted in slight bellmouthing of the half circles at each edge of the layout.  So the radius stated on the EZ Track IS CORRECT!

Thanks to all that took interest.

Yes, measured to the centerline and no suicide tracks at edges.

Regarding actual radius of EZ Track, on my layout the 22" curves work out to approx. 23-1/8, the 28" at 29-5/8 and the 33-1/4" at 33-7/8.  These measurements are on taken on half circles (180 deg.), maybe if they were full circles they would measure closer to the radius stated on the bottom of the track.  My reason for concern is that if I designed a complex layout to fit given overall dimensions it probably would have problems.

Where can I find the actual radius/diameter of the various EZ Track curve pieces?
