From 26 July 2004 D2-class trams were progressively moved to operation on route 96, displacing B-class trams that were in service at the time. In September 2013, following the introduction of the E-class trams, Yarra Trams started to move D2 class trams to Brunswick depot to operate on route 19. As of March 2017, all D1-class operate from Malvern depot, while all D2-class operate out of Brunswick depot.

Criticisms In March 2016, Time Out Magazine rated the D-Class tram the worst on the Yarra Trams network. The reasons given were a low number of seats, the uncomfortableness of the seats, a loud screech when the doors open and close and poor ride quality.
