Full project details

The Hornsby Platform 5 and Stabling Works project was a component of the NSW Government's 'Clearways' program. For the project, Laing O’Rourke constructed a stabling yard and redeveloped Hornsby Station while working in a live rail environment. 

Hornsby Station, north of Sydney, is one of the busiest rail junctions in the metropolitan system. The original four platforms handled over 530 passenger trains and 24 freight services each day, as well as daily interurban trains and regional services to Brisbane, Armidale and the North Coast. The works, which were predominantly self-delivered by Laing O’Rourke, therefore needed to be constructed adjacent to live railway, with no unplanned disruption to train services on this main arterial rail link.

Laing O’Rourke designed and constructed new track, the platform and a stabling yard to separate freight train movement, alleviating congestion in peak periods. The stabling yard holds up to six 8-car train sets to the north of the existing station, and a new 1.7 km down relief track was also constructed for freight and interurban trains. Other activities included retaining wall construction, station refurbishments, civil works and earthworks. The project was completed in 2009.

A contaminated old railway site required ground remediation in some areas to remove asbestos, in one instance immediately adjacent to a kindergarten. Proactive stakeholder consultation with the local community and best-practice work methodology resulted in the successful removal of the contaminated material. Laing O’Rourke worked with a consultant to develop a strategy to remediate and reuse the material on site, improving environmental and stakeholder outcomes.

A unique aspect of the project was the removal of a decommissioned signal box, one of only two left in New South Wales. The heritage-listed building, which dates back to 1928, was to be transferred to another part of the site to be used at a museum. Staff worked for four months to prepare the 300 tonne, two-storey signal box for the move. Non-destructive digging was used to identify hundreds of live and decommissioned cables in the process of excavating the footings and preparing a 100 m ramp to the signal box’s new location.

Key to the Hornsby Platform 5 and Stabling Works project was a safety program that promoted ownership, innovation and an open reporting culture. More than 1000 project days were worked without any lost-time injuries—a result that complemented the project’s excellent environment and community outcomes.

The success of the project saw it receive the Steve Maxwell Plate Laying Award for Best Project at the 2008 Permanent Way Institution Awards.
