Frankston,Sunbury and Belgrave trains were also delayed more than 8 per cent of the time in the 12 months to August 31,with private operator Metro Trains blaming agrowing number of trespassers for disrupting services.
Victoria paysabout $786 million a year under its current contract with Metro. It includes a 92 per cent punctuality target,so less than 8 per cent of trains can be delayed,and a 98.5 per cent reliability target,meaning less than 1.5 per cent of trains can be cancelled,skip stations or run short.
Metro has met those benchmarks over the past 12 months with a network-wide average of 92.5 per cent punctuality and 98.7 per cent reliability.
But there is significant variation across the network. Only 3.2 per cent of Glen Waverley line trains were delayed over the past year,compared with 11.9 per cent on the Craigieburn line and 10.7 per cent on the Werribee line.
The Glen Waverley line also had the least outright cancellations at 0.6 per cent. Almost four times as many trains were cancelled on the Pakenham line (2.2 per cent) and more than double on the Frankston (1.5 per cent) and Werribee (1.4 per cent) lines.
Metro’s performance has improved since 2019,when it missed its punctuality target in every month of that year.
