Ipswich and Rosewood railway line

In Queensland, Australia, the Ipswich and Rosewood line refers to the section of the Main Line to Toowoomba that has a regular suburban rail service, extending southwest from the Brisbane central business district.

The Main Line railway from Ipswich to Brisbane was opened in 1876, as part of an extension of the first railway line from Ipswich to Bigge's Camp (now Grandchester) on 31 July 1865.

Originally built as single track, the section was duplicated from 1885–87, indicating how quickly the traffic volume grew on the line. Interestingly, the Albert Bridge was built to accommodate 2 tracks in 1876, though only one was laid at the time.

The line west of Ipswich was duplicated to Wulkuraka in 1902 and to Grandchester (past Rosewood) in 1913.

The section from Roma Street to Corinda (11 km) was quadruplicated in 1963, and extended to Darra (a further 5 km) in 2011, which became the junction for the first section of the new Springfield line at that time.

The Roma Street–Darra section was the first section electrified in 1979, with the section to Ipswich electrified in 1980.

The line was electrified from Ipswich to Rosewood in 1993 while Minister for Transport was the local member.
