Alstom Wins A$114m ETCS Contract for Queensland Sunshine Coast Rail Upgrade

Australia's Queensland state government has awarded Alstom a A$114m contract to deliver ETCS Level 2 signalling for Stage 1 of The Wave rail upgrade programme on the Sunshine Coast line. The contract, awarded by Queensland's Department of Transport & Main Roads, is the first tranche of a A$354m framework agreement.

The deployment marks the first application of ETCS (European Train Control System) Level 2 — a digital signalling standard that replaces lineside signals with in-cab displays — on Queensland's main line network. Stage 1 will cover 19 km of the Sunshine Coast corridor, with completion targeted before the Brisbane 2032 Olympics. The framework structure allows for additional tranches as The Wave programme progresses across the network.

Alstom will supply the ETCS Level 2 technology alongside UGL, which holds a parallel contract under the same Stage 1 package. ETCS Level 2 eliminates the need for trackside colour-light signals by transmitting movement authorities directly to the train cab via radio, enabling closer headways and higher line capacity. The system is already deployed on European high-speed and regional networks, but remains rare on Australian heavy-haul and regional lines.

The Wave is Queensland's infrastructure programme to modernise the South East Queensland rail network, including the North Coast line to the Sunshine Coast. Stage 1 encompasses track, electrification and signalling upgrades between Brisbane and the Sunshine Coast, with the ETCS rollout forming the digital backbone. The A$354m signalling framework is the largest ETCS commitment by an Australian state government to date.

The contract value converts to approximately €69m at current exchange rates, with the full framework worth €214m. Queensland's adoption of ETCS Level 2 technology reflects a shift from legacy relay-based interlocking to interoperable digital train control. The 19 km Stage 1 installation will provide the reference deployment for subsequent phases across the South East Queensland network.

The Sunshine Coast line upgrade forms part of Queensland's preparations for increased passenger demand during the Brisbane 2032 Olympics. The ETCS installation will enable higher service frequencies on the corridor by replacing fixed-block signalling with continuous radio-based supervision. Both Alstom and UGL will deliver their respective contract scopes under the Stage 1 programme, with Queensland's Department of Transport & Main Roads managing the overall Wave infrastructure delivery.
