THE PROJECT BACKSTORY
The T3 Bankstown Line carried Sydney commuters for more than 130 years before closing in September 2024 for its conversion to metro standards. Eleven stations between Sydenham and Bankstown are being rebuilt for driverless trains, with platform screen doors, level boarding and lifts across 13 kilometres of corridor. Once services begin, a train will arrive every four minutes in the peak.
Platforms in a live rail corridor are an unforgiving place to put anything. Ducting installed there has to carry load, while staying electrically inert around traction power, and managing exposure to water. Arcadis approached ECD in late 2024 to work on this challenge with them.

WHAT WE DID
Arcadis brought ECD in after earlier work together on Victoria’s Level Crossing Removal Project and MYKI, this time to develop external platform ducting for the John Holland and Laing O’Rourke delivery team.
- Designed a bespoke external ducting system in fibreglass GRP, a material new to the ECD range, selected for its non-conductive behaviour in a live rail environment.
- Engineered the profile to bear load underfoot while remaining sealed against water in a fully exposed platform application.
- Proved the concept from first principles, taking a material ECD had never manufactured with through design, tooling and production.
- Lifted output to hold the program, introducing night shifts, weekend production and additional staff across the manufacturing floor.
- Delivery began in March 2025 and finished on time, making it the largest single project ECD had taken on.
Non-conductive by design
Fibreglass GRP removes any electrical path near traction power.
Load bearing underfoot
Built to take platform traffic without deflection or damage.
Sealed against the weather
Waterproof construction for permanent outdoor exposure.
A new material, engineered in-house
First GRP system developed by the ECD design team.
