57' iron turntable, built into the side of a hill.
Ground texture matches my Scrub3 dirt.
Based on the Virginia & Truckee turntable in Reno, NV.
The prototype was purchased used by the V&T around 1906; it served until abandonment in 1950.
Three levels of detail: table is 3722 / 1346 / 306 polygons; pit is 1989 / 1179 polygons
Revision 2: optimized table track; fixed some rotation bugs
