The first two E1-class trams entered service on 4 November 2013, and the last of the fifty on 24 April 2017. In May 2015, the State Government announced it had partially taken up the option, ordering a further 20 to a slightly modified design; the first of these entered service on 13 June 2017. This updated design focused on improved safety, in response to a significant increase in passenger injuries, and implemented measures such as glare reduction to allow improved road visibility for drivers and extra handholds and grab rails for passengers. Further extensions to this order have since been made, and as of 24 February 2020 a total of 35 E2-class trams have entered service, with another five on order. Eventually, a total of 100 E-class trams will be in service.
