=== 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}}
