From 1908 to 1909, 100 electric trams were manufactured by Duncan & Fraser of Adelaide at a cost of approximately £100 each. Up to its last tram purchase in 1953, the MTT commissioned over 300 electric trams, some of which remained in service for over 75 years. The first of 11 Bombardier Flexity Classic trams were introduced in January 2006, followed by the first of six Alstom Citadis trams in December 2009. A further three Citadis trams entered service in 2018.
