As part of the South Australian Governments $2 billion plan to revitalize the public transport network over a 10 year period, the entire existing rail passenger network was upgraded.
Coleman Rail, an ACCIONA company together with joint venture partners, were awarded the Adelaide Metropolitan Rail Revitalization project by the Department of Transport, Energy and Infrastructure.
The Adelaide Metropolitan Rail Revitalization was the centerpiece of the SA Government’s investment and transformed the metropolitan passenger rail network by delivering a number of rail initiatives including gauge standardisation of the rail network and concrete re-sleepering of the metropolitan passenger rail network using sleepers suitable for gauge conversion in the future.
Revitalization of the rail network was an extremely large and complex project, requiring a significant amount of detailed planning with many factors to consider such as developing and assessing options to minimise the disruption to commuters and the surrounding community, analysing options for alternative passenger services during construction and managing the staging of construction works.

For Coleman Rail, the Adelaide Revitalisation project consisted of several sub projects. These included, the Belair Rail Upgrade, Noarlunga Rail Revitalisation Stages 1, 2, 3 & Adelaide Yard, Gawler Rail Revitalisation Stages 1 & 4 and the Tonsley Line, collectively referred to as the ECI Upgrades.
The works included replacement of timber and steel sleepers with concrete gauge convertible sleepers, replacement of ballast, formation repairs and renewals, upgrades to and construction of new trackside drainage systems, turnout upgrades and the replacement and/or refurbishment of existing rail.
In total the Adelaide ECI Upgrade comprised the following major works:
- replacement of ballast, formation and upgrade to trackside drainage
- over 60 turnouts upgraded, including 16 new turnouts with new signalling arrangements
- more than 400,000m3 of spoil removed from site, 50km of subsoil drainage and 100km of cess drainage
- 175km of track construction (concrete sleepers and rail remediation)
- level crossing upgrades of over 30 level crossings
- over 100 pedestrian crossings managed and reinstated during construction
- replacement of 36km of rail
- rail rectification of 139km of existing rail (in excess of 10,000 defects)
- track upgrades through two major tunnels
- four significant structure upgrades of river crossings
- four main road overbridge rail upgrades
- five pedestrian subway upgrades for new track alignments
All Adelaide ECI Upgrade projects completed to date have been closed and handed over to DTEI for full operation with no outstanding quality issues.
