Editing Loading gauge (section)

=== 5 ft and Russian gauge===
In Finland, rail cars can be up to {{convert|3.4|m|ftin|abbr=on}} wide with a permitted height from {{convert|4.37|m|ftin|abbr=on}} on the sides to {{convert|5.3|m|ftin|abbr=on}} in the centre.<ref>{{cite web|date=15 December 2009|title=Lastprofiler Finland|url=http://www.greencargo.com/sv/Godsvagnar/Start/Lastprofiler/Lastprofiler-Finland/|url-status=dead|archive-url=https://web.archive.org/web/20111111100302/http://www.greencargo.com/sv/Godsvagnar/Start/Lastprofiler/Lastprofiler-Finland/|archive-date=11 November 2011|access-date=18 September 2012|publisher=Green Cargo|language=sv}}</ref> The [[track gauge]] is {{Track gauge|1524 mm|lk=on}}, differing {{cvt|4|mm|in|frac=32}} from the {{Track gauge|1 520 mm|lk=on}} Russian track gauge.

The Russian loading gauges are defined in standard GOST 9238 (ГОСТ 9238–83, ГОСТ 9238–2013) with the current 2013 standard named "Габариты железнодорожного подвижного состава и приближения строений" (construction of rolling stock clearance diagrams [official English title]).<ref name=gost9238>{{cite web|url=http://protect.gost.ru/document.aspx?control=7&id=185371|title=ГОСТ 9238-2013|date=1 July 2014|url-status=live|archive-url=https://web.archive.org/web/20180415124726/http://protect.gost.ru/document.aspx?control=7&id=185371|archive-date=15 April 2018}}</ref> It was accepted by the [[GOST|Interstate Council for Standardization, Metrology and Certification]] to be valid in Russia, Belarus, Moldova, Ukraine, Uzbekistan and Armenia.<ref name=gost9238 /> Loading gauge is generally wider than Europe, but with many exception standards.

* T: standard loading gauge
** T: 5,300&nbsp;mm height, 3,750&nbsp;mm width
** T<sub>c</sub>: 5,200&nbsp;mm height, 3,750&nbsp;mm width: for tank and dumper cars
** T<sub>pr</sub>: 5,300&nbsp;mm height, 3,500&nbsp;mm width: extra ''out-of-gauge'' cargo load for main tracks
* 1-T: guaranteed loading gauge for all ex-USSR lines including old tunnels.
** 1-T: 5,300&nbsp;mm height, 3,400&nbsp;mm width
* VM: for international stock for 1435&nbsp;mm lines, standards for different lines
** 0-VM: 4,650&nbsp;mm height, 3,250&nbsp;mm width
** 1-VM: 4,700&nbsp;mm height, 3,400&nbsp;mm width
** 02-VM: 4,650&nbsp;mm height, 3,150&nbsp;mm width
** 03-VM: 4,280&nbsp;mm height, 3,150&nbsp;mm width

The standard defines static envelopes for trains on the national network as T, T<sub>c</sub> and T<sub>pr</sub>. The static profile 1-T is the common standard on the complete 1520&nbsp;mm rail network including the CIS and Baltic states. The structure clearance is given as S, S<sub>p</sub> and S<sub>250</sub>. There is a tradition that structure clearance is much bigger than the common train sizes. For international traffic, the standard references the kinematic envelope for GC and defines a modified GC<sub>ru</sub> for its high-speed trains. For other international traffic, there are 1-T, 1-VM, 0-VM, 02-VM and 03-VM<sub>st</sub>/03-VM<sub>k</sub> for the trains and 1-SM for the structure clearance.<ref name=gost9238 />

The main static profile T allows for a maximum width of {{convert|3750|mm|ftin|frac=16|abbr=on}} rising to a maximum height of {{convert|5300|mm|ftin|frac=16|abbr=on}}. The profile T<sub>c</sub> allows that width only at a height of {{convert|3000|mm|ftin|frac=16|abbr=on}}, requiring a maximum of {{convert|3400|mm|ftin|frac=16|abbr=on}} below {{convert|1270|mm|in|frac=16|abbr=on}}, which matches with the standard for train platforms (with a height of {{convert|1100|mm|in|1|abbr=on|disp=sqbr}}). The profile T<sub>pr</sub> has the same lower frame requirement but reduces the maximum upper body width to {{convert|3500|mm|ftin|frac=16|abbr=on}}. The more universal profile 1-T has the complete body at a maximum width of {{convert|3400|mm|ftin|frac=16|abbr=on}} still rising to a height of {{convert|5300|mm|ftin|frac=16|abbr=on}}.<ref name=gost9238 /> Exceptions shall be double-stacking, maximum height shall be {{convert|6150|mm|ftin|frac=16|abbr=on}} or {{convert|6400|mm|ftin|frac=16|abbr=on}}.

The structure gauge S requires buildings to be placed at minimum of {{convert|3100|mm|ftin|frac=16|abbr=on}} from the track centreline. Bridges and tunnels must have a clearance of at least {{convert|4900|mm|ftin|frac=16|abbr=on}} wide and {{convert|6400|mm|ftin|frac=16|abbr=on}} high. The structure gauge S<sub>p</sub> for passenger platforms allows {{convert|4900|mm|ftin|frac=16|abbr=on}} only above {{convert|1100|mm|ftin|frac=16|abbr=on}} (the common platform height) requiring a width of {{convert|3840|mm|ftin|frac=16|abbr=on}} below that line.<ref name=gost9238 /> The exceptions shall be double-stacking, minimum overhead wiring height must be {{convert|6500|mm|ftin|frac=16|abbr=on}} (for maximum vehicle height of {{convert|6150|mm|ftin|frac=16|abbr=on|disp=sqbr}}) or {{convert|6750|mm|ftin|frac=16|abbr=on|disp=sqbr}} (for maximum vehicle height of {{convert|6400|mm|ftin|frac=16|abbr=on|disp=sqbr}}).

The main platform is defined to have a height of {{convert|1100|mm|in|1|abbr=on}} at a distance of {{convert|1920|mm|in|1|abbr=on}} from the center of the track to allow for trains with profile T. Low platforms at a height of {{convert|200|mm|in|1|abbr=on}} may be placed at {{convert|1745|mm|in|1|abbr=on}} from the center of the track. A medium platform is a variant of the high platform but at a height of {{convert|550|mm|in|1|abbr=on}}.<ref name=gost9238 /> The latter matches with the TSI height in Central Europe. In the earlier standard from 1983, the profile T would only be allowed to pass low platforms at {{cvt|200|mm|in|2}} while the standard high platform for cargo and passenger platforms would be placed no less than {{convert|1750|mm|in|1|abbr=on}} from the center of the track.<ref>{{cite web|url=http://vsegost.com/Catalog/43/4382.shtml|title=ГОСТ 9238-83 Габариты приближения строений и подвижного состава железных дорог колеи 1520 (1524) мм|website=vsegost.com|url-status=live|archive-url=https://web.archive.org/web/20160917235231/http://vsegost.com/Catalog/43/4382.shtml|archive-date=17 September 2016}}</ref> That matches with the T<sub>c</sub>, T<sub>pr</sub> and the universal 1-T loading gauge.
