Weren't the previous generation of trams eg R class also rigid in their design?
They were significantly shorter and had rotating bogies. The modern artics in Sydney have fixed bogies so the whole body has to twist to follow the track.
John Dunn altered the articulations on the Variotrams after the civil construction error was noticed when he did a walk through during construction. At that point it was still possible to alter the Variotrams to fix the civil stuff up. He added the ability to twist to a 2nd articulation joint.
The Urbos and Citadis are taking the curve via play the secondary suspension as they can not articulate in two dimensions at the same time.
A Citadis has already popped out a suspension component while taking that curve. (It didn't derail, just bottomed out)
