Summer rail line works will disrupt trains travelling to and from Dandenong.
A power, signalling and communications upgrade to prepare for high capacity metro trains (HCMT) will close sections of the Frankston and Cranbourne/Pakenham lines during January.
Work on removing level crossings will also take place.
Power will be switched off and buses will replace trains from Tuesday 2 to Tuesday 9 January between Flinders Street and Westall Railway Station on the Cranbourne/Pakenham line, and Flinders Street and Moorabbin on the Frankston line.
Buses will also replace trains between Caulfield and Dandenong from Wednesday 10 to Wednesday 17 January, and again between Westall and Dandenong for two weeks during February.
Those travelling to the city on affected lines during these works should allow an extra 40 to 75 minutes.
V/Line services will also be affected.
By the end of next year, all nine level crossings between Caulfield and Dandenong will be gone and the first HCMT will have arrived and be in testing ahead of its introduction to the network in early 2019.
