Probably the most fun to design and most
challenging to build, a recessed turntable is something really special in a layout. The
table could be driven by a worm gear with a button on the side or turned manually. This
feature tends to concentrate passing trains and engineers may stack up while waiting to
transit through the switchyard.Four track lines require the turntable
to be adjusted to allow passage, with only a single path bypassing the turntable
completely. The asymmetry of the turntable restricts longer trains from rotating between
track lines. Shorter trains can also be shunted to three sidings branching from the table.
