Increasing development of residential properties, employment areas and town centres in Cranbourne and Clyde is increasing demand on the Dandenong Rail Corridor, which includes the Cranbourne and Pakenham lines.

The population in the Local Government Areas covering Dandenong, Cranbourne and Pakenham are expected to increase from 585,000 people in 2015 to 793,000 by 2031, which will place pressure on the existing rail services.

The Cranbourne Line is principally limited to a single track south of Dandenong, which impacts on the ability to:

  • maintain service timetables, with current on-time performance regularly below 90%
  • run more services, with the line currently limited to four services per hour during the AM peak
  • realise the benefits specified by other major rail infrastructure investments.

Overcrowding, reduced punctuality and reduced reliability on the Cranbourne Line  is estimated to cost $154 million per year  by 2036.


Duplication of 8 km of the Cranbourne Line between Dandenong and Cranbourne provides an opportunity to increase the number of services, reduce overcrowding, and improve punctuality and service reliability.

The line may be extended to Clyde in the future, although this is not part of the current proposal.

This proposal is complementary to the Early-Stage Proposal for Melbourne rail network capacity, which is also included on the Infrastructure Priority List.
