Cogwheel steamlocomotive HG 3/4 # 4 of the Dampfbahn Furka Bergstrecke (DFB), former Furka-Oberalp-Bahn (FO), is turned on the turntable at Oberwald for the return journey to Realp.
In rail terminology, a railway turntable or wheelhouse is a device for turning railway rolling stock, usually locomotives, so that they can be moved back in the direction from which they came.
If I run into a transfer table, that might get included.
