what cross over and track would enable me to make the smallest circle 8 possible can't come up with good one that works in small area
Dear 1346dar,
Define your "small area".
2.2 x curve radius = approx. table width for a Figure 8.
5.2 x curve radius = approx. table length for a Figure 8.
The term for the X shaped track piece is "crossing".
A "crossover" has 2 identical turnouts with thier divergent routes attached to each other.
What track system are you planning to use? Atlas seems to have a better selection, at least in non-roadbed style track.
Hope this helps.
Sincerely,
Joe Satnik
