Graz 4202 (ex TARS 637) at the Tramway Museum Graz.
This car is painted in the Third Ave livery. Unfortunately they have it parked in a back corner of the barn and I was unable to get a full picture.
The car is operable, but can't be used because it is too wide for the Graz system. (In Austria the museums run their cars on the regular street routes.) The car contains a G scale trolley layout.
