Great you enjoyed the turntable (which works OK in this scenario!) robmerlo.
I saw a turntable last week, at one of our tourist rail lines, that had been extended each end to take a Garratt! I could see the welds and rivets at each end for the extensions.

Have enjoyed a good run fun ride on the turntable wonder how many times rode or drove a turn table at Traralgon Maffra Sale Mirboo nth Stratford
