Project Overview
Industry: Railway Infrastructure
Location: VIC
Duration: 2 Days
Types of Laser Used: Needle 300W
Summary: Precision Laser Cleaning (PLC) was engaged by a leading civil contractor to undertake localised lead paint removal on a rural railway bridge in Gippsland, Victoria. The project formed part of a larger refurbishment effort that involved replacing rail sections and transom structures to enhance the bridge’s strength and longevity.

The Challenges
Containment and Scaffolding: The client sought to avoid extensive scaffolding or containment measures to minimise risks and avoid interfering with the live railway operations. This ruled out traditional abrasive blasting methodologies.
Dust and Lead Paint Control Requirements: Despite the minimal containment approach, the hazardous lead-based coating required strict controls to meet EPA and WHS regulations.
Coordination with Train Schedules: The live railway meant the works had to align with the train timetable, requiring a methodology that allowed for rapid mobilisation and demobilisation to accommodate passing trains.
The Solution
Containment and Scaffolding: To minimise risks and disruption to live railway operations, PLC used Netalux Pulse Lasers. Unlike abrasive blasting, it requires no chemicals or media, allows small containment systems and eliminates large scaffolding; Our 40 kg Needle laser enables fast and efficient work.
Dust and Lead Paint Control: PLC implemented a proven lead paint removal methodology using inline HEPA extraction systems. This ensured all lead paint fumes and debris were captured at the source, protecting personnel and preventing environmental contamination.
Coordination with Train Schedules: The combination of our compact Netalux laser equipment and skilled team enabled rapid mobilisation and demobilisation. This allowed the work to be completed in phases with minimal disruption to train operations.

The Results
This project highlights the advantages of laser cleaning for lead paint removal, particularly in environments with limited access and live operational constraints. PLC’s methodology ensured quick setup and pack-down times, providing unmatched flexibility and efficiency. Laser cleaning proved to be an ideal solution for preparing surfaces for cutting and welding, offering a safe, cost-effective, and environmentally responsible approach for rail sector projects.
