LTK-designed railcarPlanning for a population surge. 

To address Sydney’s expanding population, which is expected to reach six million by the 2030s, the NSW Government sought to increase public transport options within the metropolitan region. The Government also wanted to make alternative transport options more reliable to serve the population in subregions that were placing significant demand on the existing network. An environmental assessment was conducted and determined that an extension to the light rail network would provide significant regional transport, social, and economic benefits for the existing communities within Sydney’s Inner West, as well as respond to projected population and employment growth.

LTK aided Transport for New South Wales (TfNSW) with technical support for the procurement of new 100% low-floor light rail vehicles (LRV). The requirement was introduced to meet the growing demands that resulted from the extension of the Sydney light rail system from Lilyfield to Dulwich Hill. LTK also established an operational interface between TfNSW, contract operator Transdev, LRV supplier CAF and the systems contractor John Holland. Additionally, LTK provided commissioning management for vehicles and infrastructure. This work included:

  • Reviewing design documents, test plans, and test procedures supplied by CAF
  • Conducting first article inspections and vehicle production inspections
  • Witnessing the unloading and delivery operations of vehicles
  • Supervising the on-site static and dynamic testing
  • Validating system functionalities against the design requirements and set testing methods
  • Liaising with operator, maintainer, and manufacturer to assure the work was performed in an efficient manner

The client specifically asked LTK for technical support regarding the system elements of the project during the LRV procurement phase. The LTK Team provided additional technical analysis and technical advice on the system-related aspects of the light rail network. Regular progress updates were provided to the client. LTK also collaborated frequently with the safety regulator and provided safety documents to support the safe operations of the new light rail extension.

With our expertise in construction, we were heavily involved with various elements that were undergoing commissioning, including three traction power substations, 6km of double-track overhead wiring, automatic train protection systems, and the SCADA system. The extension also required work to be performed regarding facilities and LTK was involved with the construction of nine stations with passenger information systems, and control centre and maintenance facility upgrades.

Due to the dedication of the entire project team, the project, which encompassed a heavy workload, was successfully completed on time.
