Beerburrum to Nambour (B2N) Rail Upgrade: Project Profile

The Beerburrum to Nambour (B2N) Rail Upgrade is a critical infrastructure project designed to resolve a significant bottleneck on Queensland’s North Coast Line. By duplicating the 40km single-track section, the project will substantially increase passenger and freight capacity, improve operational speeds, and enhance safety through modern signalling systems and the elimination of level crossings.

Technical Specifications

The core of the B2N project is the duplication of the rail line from a single bidirectional track to a dual-track configuration. Stage 1 involves duplicating the 20km section from Beerburrum to Glass House Mountains, which includes significant track realignment to improve geometry and allow for higher speeds. Major civil works include the construction of multiple road-over-rail bridges to replace level crossings at Barrs Road and Caloundra Street, enhancing safety and reducing road congestion. Station infrastructure will be substantially upgraded with the replacement of temporary single platforms with permanent dual platforms, new overbridges, and accessibility lifts.

A critical technology upgrade is the integration of the European Train Control System (ETCS) Level 1 and Automatic Train Protection (ATP) along the Beerwah-Nambour corridor. This advanced signalling system will provide continuous speed supervision and enforcement, significantly improving operational safety and allowing for increased traffic density on the line. The project also encompasses extensive power system upgrades to support the increased electrical load of the dual-track system and modern signalling equipment.

Key Takeaways

• Resolving a Major Bottleneck: The upgrade from a single to a dual-track system directly addresses a long-standing constraint on the North Coast Line, unlocking capacity for more frequent and reliable passenger and freight services.
• Enhancing Safety and Modernisation: The project’s commitment to eliminating level crossings and installing a modern ETCS Level 1 signalling system represents a significant step-change in operational safety and network efficiency for Queensland Rail.
• Fostering Regional Economic Growth: By improving transport connectivity to the Sunshine Coast, the B2N project is a key enabler for regional economic development, supporting population growth and facilitating more efficient supply chains.

Frequently Asked Questions (FAQ)

When will the Beerburrum to Nambour rail upgrade be finished?

Stage 1 of the Beerburrum to Nambour rail upgrade, which covers the section from Beerburrum to Glass House Mountains, is expected to be completed in 2027. The timeline for subsequent stages is subject to future funding and planning.

Who is building the B2N rail project?

The B2N rail project is a joint initiative funded by the Australian and Queensland governments. The design and construction are being delivered by key industry partners, including a joint venture between John Holland and Seymour Whyte, with design support from SMEC and WSP Australia.
