Opened in 1886, Hornsby Junction is a network of interconnected tracks serving intercity, metropolitan, and regional passenger services, as well as freight services, located within a skinny brownfield site in the Sydney suburb of Hornsby.
The Hornsby Junction Remodelling project aims to deliver faster turnaround times for trains, increase capacity, and improve service reliability for the T1 North Shore Line by incorporating new signalling and rail services.
The challenge for the design and construction teams was how to navigate the brownfield site, twisting and turning the new infrastructure to fit with the existing services, wiring and signalling, all with nothing clashing.
