Re: [TramsDownUnder] Getting back to trams ...

The original Variobahn car prototype (Chemnitz Tw601) had a radial
mechanism on the motor bogies where the sub axles could turn, the idea
being the same, to ease the car into curves. However it didn't quite
work as expected and the Chemnitz workshops welded the pivots locking
the 4 stub axles parallel. The production Variobahn/Variotrams did not
have this 'feature'.

Tw601 was the basis for the Sydney Variotrams. Our bogies are John Dunn
designs based on the German originals.
