Springfield railway line


Springfield railway line is a suburban railway line in Brisbane, Australia that branches from the Ipswich/Rosewood line after Darra railway station. Construction of the line started on, and it opened on 2 December 2013. The line was developed along with the widening of the nearby Centenary Motorway.
The line speed is rated for speeds of up to in most sections. However only the interurban multiple unit 100 and 120 series and New Generation Rollingstock trains can run at the full speed of the line. The current timetable is based on a top speed of between Richlands and Springfield stations, which is faster than the Centenary Motorway that runs alongside.

Construction and opening

Construction of the first stage of the line, to Richlands, started on, with the first sleeper being laid at Darra on the Ipswich line. The line was developed along with the widening of the nearby Centenary Motorway from two to four lanes from Darra through to the Logan Motorway.
Construction of the first station on the line, Richlands, started on, and the line was due to begin service on without service from Darra to the City due to scheduled maintenance works on the Ipswich line.
The opening was brought forward to to assist travelers from further west who could not use the Ipswich line, which was out of service due to Queensland floods.
On, work started on the second stage of the line to Springfield. The station originally proposed as Springfield Lakes station was renamed Springfield, and the one proposed as Springfield station renamed Springfield Central.
The extension to Springfield Central began service on 2 December 2013.
A proposal exists to extend the line from its present terminus at Springfield Central to Redbank Plains, Ripley Valley, Yamanto, and Ipswich station.

Route

Passengers would change for or from the Ipswich and Rosewood lines at Darra; Beenleigh, Gold Coast and Cleveland lines at Roma Street; and all other lines at Central.
The route crosses the interchange between the Logan Motorway and Centenary Motorway on a two-track viaduct more than 800 metres long. The viaduct has been designed so that its piers do not obstruct planned expansions of both roads.

Proposed extensions

In the Connecting SEQ 2031 Plan, the QLD Government has listed an UrbanLink high frequency service running from Darra to Springfield, and on to Redbank Plains via Augustine Heights, as an extension to the existing Springfield Line. It also talks about an ExpressLink between Ipswich and Ripley, via UQ Ipswich, Churchill, Yamanto and Deebing Heights; with the vital corridor between Ripley and Redbank plains being reserved for a later time after 2031.
