Been awhile, so here what I have been up to, more work on the turntable pit and bridge.
Added a pit rail from some atlas code 55 track.
Added track and walkway support to bridge, again a piece of atlas code 55.
Cut some strips (approx 10-12" width in N scale) from 1/32" basswood sheet, stain and cut to 20' length.
Started walkway platform on bridge
And cut the opening in the layout for the turntable.
