split into six separate work packages

As a specialist rail and civil contractor, Coleman Rail (an ACCIONA company) provided expert management, engineering and construction resources for all elements of the works.

The overall Regional Rail Link (RRL) project constructed dedicated tracks for regional trains through the metropolitan train system between Sunshine and Southern Cross Station, thereby removing significant bottlenecks from the rail networks.

 

The RRL project was split into six separate work packages. Coleman Rail, Lendlease and John Holland Joint Venture undertook the works for the City to Maribyrnong River (CMR) or Work Package B as part of the CMR Alliance, procured under the competitive alliance model. The CMR section was one of the most complex and challenging sections of the RRL project. 

 

Current Status

The Regional Rail Link, Work Package A, was successfully completed in March 2015.Coleman Rail’s large multi-disciplined workforce, all experienced in working in a live rail environment, allowed the reliance on subcontract resources to be minimised. This gave the project team  absolute control over all critical construction activities allowing construction time and cost to be reduced and the highest standard quality control to be achieved. This combined with meticulous planning allowed the numerous construction and commissioning occupations of the railway to be handed back on time.

General information

  • Location: Victoria, Australia
  • Contract: Alliance
  • Infrastructure: Work Package B, otherwise referred to as RRL-CMR (Regional Rail Link - City to Maribyrnong River) provided separation of the regional and suburban passenger networks from Maribyrnong to Southern Cross Station
  • Completion date: March 2015
  • Contract Value: AU$575 million

Key Details

The project provided separation of the regional and suburban passenger networks on approach and provides for independent freight train movements Victoria’s from Southern Cross station to the Maribyrnong River.

The works included; 26 kms of broad gauge, standard gauge and dual gauge track in plain line with guard rails and direct fixation. As well as significant temporary track works, traction power and staging works to minimise disruption to services, including temporary safe working systems (signalling). There were 8 new rail bridges and underpasses with arterial roads and a new rail viaduct of the Maribyrnong River (twin track, 435m long) in addition to a new RRL Flyover structure (140m long). All works were delivered in a brownfield rail corridor between Southern Cross Station (Melbourne CBD) and Hopkins Street Bridge in Footscray inner west.

Benefits

  • In general the project was delivered with an outstanding safety record, ahead of time, under AOC and with a high quality outcome
  • The communication and traffic management strategy was praised by both VicRoads and City of Melbourne as setting a new benchmark for undertaking such complicated closures in future
