=== High-speed operation === Generally, switches are designed to be safely traversed at low speed. However, it is possible to modify the simpler types of switch to allow trains to pass at high speed. More complicated switch systems, such as double slips, are restricted to low-speed operation. On European high-speed lines, it is not uncommon to find switches where a speed of {{convert|200|km/h|0|abbr=on}} or more is allowed on the diverging branch. Switches were passed over at a speed of {{convert|560|km/h|0|abbr=on}} (straight) during the French world speed run of April 2007.<ref>{{cite web |url=https://extranet.artc.com.au/docs/eng/track-civil/procedures/pc/Section3.pdf?28 |website=Extranet.ARTC.com.au |archive-url=https://web.archive.org/web/20180327043114/https://extranet.artc.com.au/docs/eng/track-civil/procedures/pc/Section3.pdf?28 |title=Points and Crossings |archive-date=27 March 2018 |access-date=25 September 2022 }}</ref> The US [[Federal Railroad Administration]] has published the speed limits for higher-speed turnouts with {{abbr|No.|Number}} 26.5 turnout that has speed limit of {{cvt|60|mph|0}} and {{abbr|No.|Number}} 32.7 with speed limit of {{cvt|80|mph|0}}.<ref name="63 FR 39343">{{cite web |title=63 FR 39343 β Automatic Train Control and Advanced Civil Speed Enforcement System; Northeast Corridor Railroads |url=http://www.gpo.gov/fdsys/granule/FR-1998-07-22/98-19431/content-detail.html |publisher=Federal Railroad Administration |access-date=21 October 2012 }}</ref>
