🚆 Blue Mountains Line Faces Delays Due to St Marys Track Repairs

Commuters on the Blue Mountains Line are being advised to brace for significant disruptions today, Monday, November 10, 2025, with urgent track repairs at St Marys causing extensive delays and changes to services. Transport for NSW issued an alert indicating that trains may be stopping at different platforms and large gaps between services are to be expected, impacting both the Blue Mountains Line and the Western Line.

Passengers travelling to and from the Blue Mountains National Park region should allow extra travel time and are strongly encouraged to listen for station announcements and check transport apps before commencing their journeys. The repairs, classified as urgent maintenance, highlight the ongoing need for infrastructure upkeep across the rail network.

Trackwork, whether planned or urgent, is essential for maintaining the high standards of safety and reliability expected on public transport networks. Transport for NSW regularly undertakes such work to fix and upgrade critical infrastructure. Areas like St Marys are routinely subject to various maintenance activities, including overhead wiring rebuilds, signalling works, and track defect removal, all aimed at improving overall network reliability.

The Blue Mountains Line has, unfortunately, faced ongoing challenges with punctuality. Intercity services, including those connecting to our region, have struggled to meet performance targets, with the Blue Mountains Line recording its worst on-time performance in the last financial year, with only 69% of services running as scheduled. Factors contributing to these reliability issues often include the age of infrastructure, such as older tunnels and bridges, and impacts from severe weather events.

Transport for NSW appreciates commuters' patience and understanding as crews work diligently to complete these vital repairs. For the latest real-time updates, visit the Transport for NSW website or use their official apps.
