I'm not sure if this question properly belongs here or not; if it's in the wrong location then one of the moderators will move it to a more appropriate location.
Where a dual-gauge turntable is fitted on a conventional 3-rail system, how do traincrews turn the narrower-gauge loco? Would I be correct in thinking that the middle rail moves towards/away from the adjacent broader-gauge rail while the other broader-gauge rail separates to give 4 rails on the turntable lead?

Re: Dual-Gauge operations
All the Google evidence shows that there were four rails on the turntable.
See here for the way to go from three to four rails.

Re: Dual-Gauge operations
Thank you gents. I think I'll abandon plans for a dual-gauge turntable and run the narrower-gauge units backwards instead...

Re: Dual-Gauge operations
As shown in the photo I linked to, you don't need a switch to get to four rails. It would be an interesting bit of track to build and you only need one on the lead to the turntable.
