Hi Tony,
I think you are probably right - some of the Z3s will get bumped from
the list, and given that a lot of Z3s have already been done, some As
may also get bumped..
There are 100 new trams to come - so on a one for one basis only 70 As
and Z3s are needed to maintain current fleet numbers.
Both of these classes require being stripped down to bare frame level -
to replace insulation. Both also have asbestos contamination in the
sealants - so the stripping is more expensive.
I can't imagine a major rebuild of the As into articulated or coupled
sets - they are a bit old for that and they are not low floor.
