It was permitted to turn from Spencer Street into Flinders Street on a "substandard" radius curve but only under strictly controlled conditions with ground staff observing the compression and extension of components between the modules and at less than walking pace. The only reason it was allowed to make that turn was to get it onto MCG event shuttles using Simpson Street siding as a turnback. It was not permitted to make any other right-angle street-corner turns due to the radius of our older track and its greater width posing a slight risk of striking an adjacent vehicle on the opposite track. As such the exact design could not have been used in Melbourne. Just as with the Citadis trams a special "Melbourne-only" version would have had to be designed and built which I understand was considered too costly despite offers being made to have them built or assembled locally at Dandenong or Ballarat.But the Mulhouse Citadis, even though selected from another European city with a second generation tramway, doesn't seem to have the same problem with tight curves, and nor did that CombinoPlus that was demonstrated here. The Eurotram is thus much more strictly adapted to the standard LRT specifications than Citadis, let alone the Combino.
