The Victorian budget has been presented today and includes 100 more trams.
The Age reports:
A total of $1.48 billion will be spent on building 100 new modern accessible trams to retire the ageing A and Z-class trams. What will be the largest tram order in decades will include an order for new E-Class trams and possibly another variety, will also go towards a new maintenance facility in Melbourne’s north-west to support 1900 jobs.
I'm guessing that the "new maintenance facility" will be somewhere around Airport West and Essendon depot is likely to close.
Route 59 loadings easily justify E class trams, but there is nowhere to put them.
