The 2008/09 State Budget provided the biggest single investment ever by a State Government in Adelaide's public transport system. Over a ten year period, $2.6 billion is being invested to transform the network into a sustainable state-of-the-art system, providing faster, cleaner and more efficient services for customers.

Included as part of this $2.6 billion public transport investment is the purchase of new trains and trams.  This investment includes:

• the purchase of 66 new electric railcars (first delivery expected in 2012)
• refurbishment of the entire TransAdelaide fleet of 3000-class rail cars
• conversion of 54 of the 3000-class rail cars to electric operation
• retention of the remainder of the refurbished rail cars for operation on the Belair line
• six near new Citadis Euro-Trams boosting the modern tram fleet by 50%.
