Dual-Gauge operations

Post by mec_alf » Thu Apr 06, 2017 8:45 am

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?

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.

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

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.
