A summer blitz will begin in January to prepare for the massive transport projects currently underway.

The Cranbourne and Pakenham lines will receive one of the biggest ever upgrades to power, signalling and communications.

The upgrade will allow new, High Capacity Metro Trains to run from mid-2019 onwards. The trains will carry 20 per cent more passengers than current models.

At this time, the eastern entrance to the Metro Tunnel will also begin at South Yarra, as well as some much-needed maintenance across the road, rail and tram network.

To allow these works to be carried out, buses and coaches will replace trains from 2 to 13 January on the following lines:

  • Cranbourne and Pakenham, between Flinders Street and Westall stations
  • Frankston, between Flinders Street and Moorabbin stations
  • Gippsland, between Southern Cross and Bairnsdale stations.

Buses and coaches will also replace trains on these lines during January:

  • Belgrave/Lilydale, Glen Waverley and Alamein lines, between Flinders Street and Burnley stations on 12 and 13 January
  • Sandringham line, between Flinders Street and Elsternwick stations on the from 2 to 6 January
  • Bendigo, Swan Hill and Echuca lines, from 12 to 27 January
  • On parts of the Sunbury, Werribee and Williamstown lines between 13 and 16 January.

Other major works occurring around this period include:

  • buses replacing trams on Toorak Road tram Route 75, from 3 to 12 January
  • an intersection closure at Yan Yean, Diamond Creek and Aqueduct roads in Plenty, from 2 to 24 January.
