Same attitude as Transport for New South Wales, who do not believe that they could
possibly learn anything from Sydney Tramways - who ran one of the world's largest
tramways - and certainly the largest in the Southern hemisphere (though I suspect San
Paulo may have been bigger, in number of trams if not if route miles. Nor do they believe
they can learn anything from Melbourne - who only run those tiny old-fashioned trams!

A bit of the "I've been appointed as Manager, and therefore I can manage anything! I
don't need to know anything about it."

Reading between the lines, it would appear that the main problem is Network Rail, who seem
to have the following attitude: "We have never done this before and so do not know how to
do it. We need time to think about it, solve the problem and do the design work. It
doesn't matter that somebody else has done all this already and has the answers! We are
the world experts and we know everything, so just sit there and wait while we fiddle
about." My words but that seems to be the attitude.

Something Sydney did back in 1996 with the Variotram and it's hybrid profile wheels.

They are literally re-inventing an already re-invented wheel.

The attached is part of a drawing with an original date of 1995 and it makes reference to
an even older ABB drawing. And presumably Karlsruhe had to solve this issue 'way back'.

The key item is the stepped wheel back.

But not CAF, Vossloh Citylink. Vossloh rail has recently been acquired by Stadler.

Tram-train pioneer Karlsruhe have been getting them too. Sheffield's ones are based on the
Karlsruhe ones.

An only just going into service now, the first was delivered in November 2015! Nearly 2
years getting in the way in the depot before being pressed into passenger service.

And TfNSW looks to the UK to for 'expertise'.
