Sydney's first purpose-built ROC

A W Edwards delivered Sydney’s first purpose-built Rail Operations Centre (ROC) for Sydney Trains, the New South Wales Government Department responsible for providing the public train service in Sydney, Australia. The facility brings together several critical departments of Sydney Trains that are responsible for controlling the rail network with the aim of increasing efficiencies and reducing response times during unscheduled interruptions.

The facility is classified as “critical infrastructure” to the NSW state government, meaning a heightened focus on the buildings function including dual services redundancies and an increased resistance to bomb blast being incorporated in the design and delivery. The four-level building design posed a number of technical challenges that were overcome by the A W Edwards team to ensure a successful project delivery.

900 tones of reinforced steel
8 meters of high-vaulted ceilings
10,740 m² of building size

World-breaking records

The facility is characterised by its solid concrete base from which two large brickwork arches springs from, the larger of which spans over 55m – the largest of its kind in Australia. The Control Room houses one of the world’s largest LED screens measuring 33m long and 3.6m high, the largest of its kind in the World.

The criticality of the building to Sydney’s public transport system requires the facility to be operational 24 hours a day, 365 days of the year. It accommodates 450 people when fully operational.
