=== 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.

=== Iberian gauge ===
{{main|Iberian-gauge railways}}In Spain, rail cars can be up to 3.44 m (11&nbsp;ft 3.5 in) wide with a permitted height of 4.33 m (14&nbsp;ft 2.5 in) and this loading gauge is called iberian loading gauge. It is the standard loading gauge for conventional (iberian gauge) railways in Spain.

In Portugal, there are three railway loading gauge standards for conventional (iberian gauge) railways: Gabarito PT b, Gabarito PT b+ and Gabarito PT c. Gabarito PT b (also called CPb) and Gabarito PT b+ (also called CPb+) allow rail cars to be 3.44 m (11&nbsp;ft 3.5 in) wide with a permitted height of 4.5 m (14&nbsp;ft 9 in), although CPb+ has a slightly larger profile area. Gabarito PT c allows rail cars to be 3.44 m (11&nbsp;ft 3.5 in) wide with a permitted height of 4.7 m (15&nbsp;ft 5 in). Gabarito PT b and PT b+ are both used, being PT b+ more common overall. Gabarito PT c is currently not used. In Lisbon, there is a suburban railway line, the [[Cascais Line]], that follows a fourth non-standard loading gauge.{{expand section|date=August 2020}}
