X'Trapolis 100

The X'Trapolis 100 is a type of single deck electric multiple unit part of Alstom's X'Trapolis family of trains, operated in Melbourne, Victoria, Australia and Valparaíso, Chile. As a partner of the Melbourne Transport Enterprises consortium, which was the new operator of the Hillside Trains network (later Connex Melbourne), it was announced in 1999 that Alstom would supply and deliver new trains to the Hillside Trains network. When the trains were originally introduced to the suburban network in 2002, the trains operated only on the former Hillside Trains network (consisting of the Burnley and Clifton Hill group lines), and did not run revenue services elsewhere operated by M>Train on the Bayside Trains half of the system. Although the two networks merged in 2004, when Connex took over all operations, the X'trapolis units still did not operate on the Bayside system at the time. On 22 October 2014, the operation of X'Trapolis 100 trains was expanded to include lines on the former Bayside Trains network with the Frankston line being cleared for their operation and initially running two weekday morning-peak services. On 20 November 2016, X'Trapolis 100 trains were expanded to full-time running on the Frankston line and began operating services on the Werribee and Williamstown lines the same day. In November 2018, X'Trapolis 100 trains’ operations were expanded to the Flemington Racecourse line. X'Trapolis 100 trains had run on the Burnley, Clifton Hill and Cross-City groups, with all services operating with 6-car trains throughout the day except the Alamein (Camberwell - Alamein) and Williamstown (Newport - Williamstown) shuttles which runs with 3-car trains during shuttle operations off-peak and on weekends. The trains also serve the Flemington Racecourse line when services operate there, operating to both Showgrounds and Flemington Racecourse stations. However, the Flemington Racecourse Line only runs on special occasions.
