Taking the wagon turntable a stage further to create what looks like a typical turntable with pit. The pit is flat, the whole unit is same thickness as standard track, so needs no ho;e cut in baseboard. Could be used on its own, but it fits in new 180 degrees turntable bases which raise it by 3.5mm, and can then be operated remotely.
This version is wood topped 84mm diameter 16.5mm gauge . Fit code 100 rail.
