Several people have cut track in half and use the cut side toward the gap.
For example for a turn table you'd use 1 cut track (two 1/2's) for the turn
table itself and 1 cut track (two 1/2's) for every two radial sidings.
However Kim Toll, another member of PNLTC, created some dynamic bridges that
simply posotion the tracks end-to-end without connecting them or cutting
them and the trains seem to traverse the gap with no problems.
BTW Ben Fleskes has completed I believe 3 or 4 iterations of turntables over
the last four years. See Ben's page at
http://www.geocities.com/CapeCanaveral/Hangar/1857/benspage.htm
or
www.pnltc.org (specifically
http://www.pnltc.org/Gal_PDX_GATS_Q199/yard/Gal_PDX_GATS_Q199_yard.html)
His latest is the best and will be shown in a few weeks at GATS in Portland, OR.

| (...) Larry, thanks for the pointers. I just got trains for the first time this December and this coupled with talking to Jim Rosikiewicz about gearing problems for his turntable at the last GardenSLUG meeting has had me thinking about how to do (...)
