Rail network in South East Queensland

Queensland Rail operates ten suburban lines and three interurban lines. Centring in the Brisbane City, it extends as far as Gympie in the north, Varsity Lakes in the south, Rosewood in the west, and Cleveland in the east to Moreton Bay.

Each line is ascribed a colour and name on all Queensland Rail signage and marketing collateral including timetables, posters and maps. There are 153 stations in the Queensland Rail City network.

TransLink operates several bus routes along corridors on behalf of QR where the railway line has been closed to passenger traffic or supplements low-patronage lines at specific times of the day.

The Brisbane and south east corner of Queensland has experienced significant population growth, with approximately one million more people living in the area over the last 20 years and a forecast population of more than 3.8 million by 2026. This growth, along with a heightened awareness of the environment and increasing petrol prices, has placed an unprecedented demand on public transport and its infrastructure; Citytrain has reported successive patronage increases of 9% in both the 2005–2006 and 2006–2007 financial years, and a 6.6% increase in the 2007–2008 financial year.

To respond to this demand, the Government of Queensland created the South East Queensland Infrastructure Plan and Program to manage the investment in new transport infrastructure, amongst other areas. QR, in response, created the SEQIPRAIL office to manage and deliver rail components of the plan.

A third track was laid between Salisbury and Kuraby stations, a length of 9.5 km (5.9 mi). Previously two tracks, the added capacity allows Gold Coast line services to operate with less chance of delays. Seven railway stations along the section were significantly upgraded. The project was commissioned on 2 March 2008.
