Re: Photo - Not No such thing as 3-rail TT ,,,

hmm, interesting thing, the turntable at Vevey!
As far as I know the white building is still in use and an old electric railcar (Triebwagen) is stored inside, waiting for restoration.
In Vevey there have been a few industries that used to be served by SG and NG freight cars.
In the distance you can see the NG "terminal" and far right, behind the hill/white building there is one of the main shops of the meter gauge line. Maybe this is the reason for the dual gauge TT, they used tu turn equipment for work on them. They usually did not turn any equipment, this line was electric from the beginning.

btw. on a branch of this former meter gauge network there is the shotrt but very beautifull Blonay-Chamby museum railroad with meter gauge equipment from all over Europe.
