Editing Loading gauge (section)

=== Australia ===
The standard gauge lines of [[New South Wales Government Railways]] allowed for a width of {{cvt|9|ft|6|in|m}} until 1910, after a conference of the states created a new standard of {{cvt|10|ft|6|in|m}}, with corresponding increase in track centres. The narrow widths have mostly been eliminated, except, for example, at the mainline platforms at [[Gosford railway station|Gosford]] and some sidings. The longest carriages are {{cvt|72|ft |6|in|m|2}}.{{Citation needed|date=November 2021}}

The [[Commonwealth Railways]] adopted the national standard of {{cvt|10|ft|6|in|m}} when they were established in 1912, although no connection with New South Wales was made until 1970.<!-- It was argued that rolling stock utilisation would be improved if they did connect. However the loading gauge of the two systems made this problematic as the loading gauge of NSW was smaller. However CR rolling stock built to the NSW loading gauge could work through. -->{{Citation needed|date=November 2021}}

A [[New South Wales T set|T set]] of the late 1980s was {{convert|3000|mm|ftin|1|abbr=on}} wide. Track centres from [[Penrith railway station, Sydney|Penrith]] to [[Mount Victoria railway station|Mount Victoria]] and [[Gosford railway station|Gosford]] and [[Wyong railway station|Wyong]] have been gradually widened to suit. The [[New South Wales D set|D set]] intercity sets are however {{convert|3100|mm|ftin|1|abbr=on}} wide, so further, costly modification was required beyond [[Springwood railway station|Springwood]],<ref>[https://www.smh.com.au/national/nsw/new-intercity-trains-too-wide-for-rail-line-to-stations-in-blue-mountains-20161005-grvmns.html New intercity trains too wide for rail line to stations in Blue Mountains] ''[[Sydney Morning Herald]]'' 5 October 2016</ref> which was completed in 2020.<ref>{{cite web | url=https://www.bluemountainsgazette.com.au/story/6848014/rail-upgrade-completed-to-fit-new-trains-on-blue-mountains-line/ |title=Rail upgrade completed to fit new trains on Blue Mountains Line |work=[[Blue Mountains Gazette]]|first=Damien | last=Madigan | date=2020-07-24 |access-date=2021-06-11}}</ref>

The [[Kwinana railway line|Kwinana]], [[Eastern Railway, Western Australia|Eastern]] and [[Eastern Goldfields Railway|Eastern Goldfields]] lines in [[Western Australia]] were built with a loading gauge of {{cvt|12|ft|mm}} wide and {{cvt|20|ft|mm}} tall to allow for trailer on flatcar (TOFC) traffic when converted to dual gauge in the 1960s.<ref>[https://web.archive.org/web/20211118152224/https://portal.engineersaustralia.org.au/system/files/engineering-heritage-australia/nomination-title/HRP.WA%20Standard%20Gauge%20Railway%20Kalgoorlie%20to%20Perth.Nomination.Dec%202012.pdf Nomination of Western Australian Standard Gauge Railway for an Engineering Heritage Australia Heritage Recognition Award] [[Engineers Australia]] September 2011</ref>
