South Yarra Station is set for a $12 million makeover thanks to an election sweetener as Labor targets marginal Greens seat Prahran.
The entrance to the train station on Toorak Road will be widened and the layout changed to make the station larger, with work to start in mid-2019 and be competed by the end of the year.
Prahran was a key battlefield in the 2014 state election, with the Greens winning the seat by nearly 300 votes.
“These works, combined with the Metro Tunnel, will mean less queues and more trains for South Yarra Station," Transport Minister Jacinta Allan said.
“We know South Yarra is busy – that’s why we’re making it quicker and easier to get out of the station, particularly during the peak.”
The government had been under pressure to upgrade South Yarra station to win back the seat from Greens MP Sam Hibbins.
The Greens and the Coalition have attacked Labor for not building an interchange at South Yarra as part of the Melbourne Metro Tunnel, with both parties promising to build the interchange if elected in November.
Nearly 32,000 people use the station everyday, according to Stonnington Council, with 20,000 people set to move into the area over the next two decades.
The council has warned the station is "chronically over capacity" and in urgent need of an upgrade.
The government has also indicated that tram stops opposite the station will be upgraded to improve disabled access between the tram stop and station.
Further planning work will be done to make the station more accessible. It does not have a lift or escalators.
The government has also trumpted the benefits of the $11 billion Melbourne Metro Tunnel to commuters on the Frankston, Sandringham and Cranbourne/Pakenham lines.
High Capacity Trains, which will start running along the Cranbourne/Pakenham line from next year, and then through the Metro Tunnel when it is complete, will comprise seven carriages, and carry up to 1100 passengers.
This is up from 900 passengers fitting into the six-carriage trains now used on Melbourne's rail network.
Platforms in the Metro Tunnel will be built to accommodate extending the trains to 10 carriages. The extended High Capacity Trains will be able to carry 1570 passengers.
