units, and an additional intermediate car to be inserted into an existing two-car unit, with an extra four carriages added in February 2009. The final unit of the order was delivered in September 2011. With the availability of improved technologies for train control, from mid-2012, sets 3VL30, 3VL40 and 3VL50 were selected by Bombardier as test sets for equipment upgrades, in order to minimise the number of sets containing non-standard systems. In November 2012, the State Government announced an additional 40 carriages will be delivered between 2014 and 2016. The order comprised seven additional 3-car sets plus 19 intermediate cars to increase the remaining 2-car sets to 3-cars. In March 2014, the order for 40 carriages was increased to 43. Further orders were placed for 21 carriages In May 2015 and 27 carriages in April 2016. All 2 carriage VLocity sets had been converted to 3 carriage sets by May 2018. In December 2017, a further nine sets were ordered. Once all have been delivered, the fleet will comprise 88 3-car sets. Of these, sets 76-79 will be of a modified configuration, with a single toilet per three-carriage set instead of two, improvements to CCTV, downrating of the engines to 650 hp each for fuel economy and altered standing and seating arrangements. Sets from 80 to 88 will revert to two toilets with modified seating and a different front to accommodate a safer driving cabin. As of 6 November 2020 units 80-88 have entered revenue service. After jockey Michelle Payne won the 2015 Melbourne Cup horse race riding Prince of Penzance, becoming the first female jockey to win the race, set 3VL9 was named Michelle Payne in honour of her regional Victorian ancestry. The set was the first VLocity to be named and the first V/Line train to be named since the Sprinters in the late 20th century. In the 2018 Victorian state election campaign, the Andrews government promised that, if re-elected, it would place an order for 18 additional three-car VLocity sets to be delivered from 2021. In the 2022 Victorian state election campaign, the Andrews Government promised that, if re-elected, it would place an order for an additional 23 three-car VLocity sets, as part of a promise to boost regional weekend services. The Government also committed to introucing nine-car VLocity trains to service the Melton railway line in Melbourne's west. Wheel wear restrictions In January 2016, V/Line removed
