List of gauge conversions

Template:Short description Template:Use dmy dates Template:Sidebar track gauge This is a list of notable railway track gauge conversions, railway lines where the distance between the rails is broadened or narrowed. Conversions to broader gauge are generally to accommodate heavier loads or for wider cars, while conversions to narrower gauge tend to be for compatibility with other lines on a rail network. This list also contains instances of lines already prepared for conversion and those which are planned to be converted.

New gauge (mm)	Original (mm)	Date	Flag & Location	Description
Template:RailGauge	Template:RailGauge		Angola	Luanda Railway
Template:RailGauge	Template:RailGauge	1950s	Template:Flagu	Moçâmedes Railway
Template:RailGauge	Template:RailGauge	1885	Template:Flagu Template:Flagu	Rail transport in Tasmania Partially converted to dual gauge as intermediate stage.
Template:RailGauge	Template:RailGauge	1970	Australia Template:Flagu	Transcontinental line: Broken Hill to Port Augusta and Kalgoorlie to Perth as part of the Sydney–Perth rail corridor.
Template:RailGauge	Template:RailGauge	1980	Template:Flagu Template:Flagu	Completion of the penultimate link in the Adelaide–Darwin rail corridor, from Tarcoola to Alice Springs. The new line replaced the ancient narrow-gauge Central Australia Railway that was on a different, more floodprone alignment.
Template:RailGauge	Template:RailGauge	1990-1995	Template:Flagu Template:Flagu Template:Flagu	Melbourne–Adelaide rail corridor – of convertible sleepers installed in 1990 to facilitate quick conversion in 1995.
Template:RailGauge	Template:RailGauge	2004	Template:Flagu Template:Flagu	Completion of the final link in the Adelaide–Darwin rail corridor, from Alice Springs to Darwin. For about half the distance, the new line replaced the ancient narrow-gauge North Australia Railway that was closed in 1976.
Template:RailGauge	Template:RailGauge	2008–2010	Template:Flagu Template:Flagu	North East railway line in Victoria. A section between Seymour and Albury was converted, changing two parallel tracks of different gauges to double track. The Oaklands line that would otherwise have been left as an orphan was converted in 2009. The cost of converting this line has been estimated as just over Template:Currency.
Template:RailGauge	Template:RailGauge	2012	Template:Flagu Template:Flagu	South Australia planned to convert its suburban (broad gauge) network to standard gauge in 2012, in conjunction with proposed electrification works. The Outer Harbor and Belair lines were rebuilt with gauge convertible sleepers and re-sleepering of the Gawler line commenced in 2010. The Seaford line was to commence once the Gawler line was completed. However, both gauge conversion and electrification works were suspended due to funding constraints, with work unlikely to proceed for the foreseeable future.Template:Update inline
Template:RailGauge (temporary)	Template:RailGauge	1950s	Template:Flagu Template:Flagu	The Mount Gambier line in South Australia was fitted with some 3-gauge steel sleepers when it was "temporarily" converted, pending later proposed conversion to Template:RailGauge (which did not occur, the line being abandoned instead).
Template:RailGauge	Template:RailGauge	1927	Template:Flagu Template:Flagu	The break of gauge between the broad and narrow gauge lines moved to Hamley Bridge "only" 78km short of Adelaide and Port Adelaide. The narrow gauge train could reach this break of gauge after travelling 1260km from Alice Springs.
Template:RailGauge	Template:RailGauge	Proposed	Template:Flagu Template:Flagu	In Western Australia, the narrow-gauge iron ore railways serving Geraldton port and the new port at Oakajee will be designed for ease of conversion to standard gauge.Template:Update inline
Template:RailGauge	Template:RailGauge	2016–present	Template:Flagu Template:Flagu	In Victoria, several wheat lines amounting to about of track, were (or are to be) converted to standard gauge, including: Maryborough to Mildura, Yelta and Murrayville; Sea Lake and Manangatang. Lines will be converted to dual gauge between Gheringhap to Maryborough. This is part of the Murray Basin Rail Project.
Template:RailGauge	Template:RailGauge	2026s	Template:Flagu Template:Flagu	The Inland Railway line from Melbourne to Brisbane of 1600 km length includes about 300 km of dual gauge that improves the curves and gradients of the original Brisbane to Toowoomba line. This dual gauge replaces the narrow gauge that was chosen to enable cheap 100m radius curves and 2% gradients.
