The state opposition has called for Premier Jacinta Allan to release updated costings for the Suburban Rail Loop instead of projected travel times.
A $34.5 billion price tag for Suburban Rail Loop East was announced in 2021 and has not been updated since, despite a 21 per cent increase in construction costs in Australia.
The Allan government released new transport modelling for the SRL on Sunday, showing passengers could save up to 40 minutes in travel time once the first stage of the project opens in 2035.
Trips between Cheltenham and Box Hill – the stations on opposite ends of SRL East – are forecast to take just 22 minutes during peak hour, more than 30 minutes quicker than current train journeys and driving.
