A few questions about available roundhouses and turntables. In terms of geometry, I know that Marklin has a roundhouse designed to work with their turntable, and I know there is a Nansen Street roundhouse designed to work with a RLW turntable.
Does anyone have some dimensions/specs/plans on any of these? Maybe more importantly, will the Nansen roundhouse work with the Marklin turntable? That would be a good setup for me.
