Cyber Security Baseline Assessment for City Rail Link, Auckland
The Challenge City Rail Link is a new 3.5km dual-bore tunnel under Auckland connecting into existing brownfield operating areas of the Kiwi Rail network — one of New Zealand’s largest rail infrastructure projects. The project was being delivered primarily through an alliance model, with separate operating and signalling networks run by Auckland Transport and KiwiRail […]
ARTC — Electrical & Earthing Design
The Challenge ARTC was developing a new greenfield Wayside Monitoring Location at Korunye (53.50 km) on the East–West rail line between Two Wells and Mallala, South Australia. The site required new wayside monitoring equipment, an equipment building and a dedicated mains power supply. The installation included a Hot Bearing Detector / Hot Wheel Detector (HBD/HWD) […]
Customer Counting & Tracking
The Challenge Questacon’s distinctive building design presented a complex environment for CCTV deployment. Obstructions throughout the facility, together with constrained cable pathways and mounting locations, meant that conventional camera placement could not always provide the required coverage. The dynamic nature and configuration of the exhibits also needed to be considered when determining the most suitable […]
V/Line — Identity & Access Management Design
The Challenge V/Line needed to improve cyber resilience across its Operational Control System network by restricting unnecessary access to critical OCS/TCS assets and establishing a centralised Identity and Access Management (IAM) system with AAA and 802.1x support. Without a structured IAM framework, the risk of unauthorised access to safety-critical rail infrastructure remained unacceptably high and […]
V/Line MTO — New Train Control Desk
The Challenge V/Line needed to alleviate the workload of Bendigo Train Controllers and accommodate additional services on the Bendigo corridor by adding a new Train Control Workstation at Centrol IOC. The existing Bendigo WestCAD system was obsolete, making a conventional new workstation installation impractical and requiring an innovative alternative technical solution. The Solution L2iQ designed […]
V/Line — Virtualisation of Obsolete Train Control Systems
The Challenge V/Line operated multiple Train Control platforms — Bendigo WestCAD, Aspectus and Melbourne Metro Phoenix — on obsolete, unsupported hardware running end-of-life operating systems (Windows XP, Windows 7, Windows Server 2016). This created significant and growing risks of hardware failure, security vulnerabilities and loss of vendor support, with no viable path to continued safe […]
V/Line — Train Control System Asset Class Strategy
The Challenge V/Line required a comprehensive strategic framework for managing its Train Control System assets across their full lifecycle. Without a rigorous asset class strategy, investment decisions were reactive, data quality was inconsistent, and the organisation lacked the visibility needed to understand lifecycle costs, obsolescence risks, and the funding requirements for maintaining a reliable and […]
V/Line — OCS Network Infrastructure Uplift
The Challenge V/Line’s Operational Control System (OCS) network required significant infrastructure uplift across multiple domains to support the Regional Rail Revival program, improve cyber readiness, and address performance and visibility gaps across the core routing, distribution switching and WAN layers. The work spanned multiple concurrent projects across a live operational network. The Solution L2iQ initially […]
Sydney Metro — Western Sydney Airport Rail
The Challenge The Western Sydney Airport Metro Rail project required specialist technical expertise in Communications systems to develop a credible installation strategy, programme, and resource analysis for one of Australia’s most significant rail infrastructure investments. The scale, complexity and airport operational interface requirements made this a technically demanding engagement from day one. The Solution L2iQ […]
Sydney Metro — Nozomi OT Security Monitoring
The Challenge Sydney Metro required improved visibility and monitoring of their operational technology environments and key rail sub-systems. Existing tools provided limited insight into OT network traffic, leaving significant gaps in real-time threat detection and asset visibility across critical rail infrastructure — making it difficult to identify and respond to OT security incidents in a […]
