That article does not give much detail about the new trams aside from the number and the projected cost.

At a webinar this week Ben Phyland, the Head of Rolling Stock Development with Victoria's Department of Transport provided more detail of the project and the trams.

* The 100 new trams to be ordered will replace 130 Z and A class trams
- meaning that at least another 100 will be required to retire the Bs.
* The new trams peak current demand must not be more than 600A (Es
peak at 1200A).  This to be achieved by using on-board storage to
smooth the spikes on demand.  It is the intention that this will
reduce the need for extra sub-stations. It’s not practical to
retrofit batteries or 'super capacitors' to existing trams – too
many differences in structure and controls.  Batteries typically add
200 to 500kg to a tram.  On board storage is aimed at reducing spike
demand from the power system and is not intended to allow 'trolley
wire free' operations - although it could for short distances.
* The new trams will be approximately the length of a B and  will thus
fit in current depots plus the new depot to be built on a parcel of
land in the west - close to purchase.  All existing depots will be
retained. There is a possibility of apartment development above some
depots at some stage in the future.
* “Trackless Trams” are not being considered as part of this project.
* New trams will have some form of collision avoidance technology –
but it is hard to implement in shared traffic lanes.
* Fixed bogie designs are not precluded from proposals from the two
potential suppliers (Alstom and CAF/UGL) for Melbourne’s  new tram.
* Vic would like to see National Standards for trams and related
equipment adopted to allow sharing of parts etc and thus get lower
bulk prices.
