I've asked this before, but got no definite answer. Photos in older books show two overlapping turntables at the engine depot in Koln, Germany. Does anyone know if these still exist? A search on the internet found only the roundhouse and turntable shown at the link below. Was this part of the twin-turntable setup that was later reduced in size?
