A broad gauge, it is the second-widest gauge in regular use anywhere in the world, with only Indian gauge railways, 5 ft 6 in (1,676 mm), being wider (by 8 mm (5 ⁄ 16 in)). As finally established in 1955, [ 1 ] the Iberian gauge is a compromise between the similar, but slightly different, gauges adopted as respective national standards in ...
In South America, Argentina and Chile use 1,676 mm (5 ft 6 in) track gauge, as well as 1,000 mm (3 ft 3 + 3 ⁄ 8 in) or metre gauge. Brazil uses 1,600 mm (5 ft 3 in) (known as "Irish gauge", most common for passenger services and a few corridors in the Southeast) and 1,000 mm (3 ft 3 + 3 ⁄ 8 in) (known as "narrow gauge" or "metre gauge", most common for cargo services).
Narrower gauge railways usually cost less to build because they are usually lighter in construction, using smaller cars and locomotives (smaller loading gauge), as well as smaller bridges, smaller tunnels (smaller structure gauge). [27] Narrow gauge is thus often used in mountainous terrain, where the savings in civil engineering work can be ...
In 1999, a gauge-changer was installed at Tornio at the Finnish end of the dual-gauge section between Haparanda and Tornio, for use with variable gauge freight wagons. [45] The Tornio gauge changer is a Rafil design from Germany; a similar Talgo-RD gauge changer at the Haparanda end used to exist, but was removed [46] as it required de-icing in ...
Standard gauge is defined both in metric and in imperial units. It is also the best-known gauge worldwide; 55% of the world uses this track. In 2020, China’s rail network is standard gauge, with around 79,685 km (49,514 mi) of line. [92] 1,440 mm 4 ft 8 + 11 ⁄ 16 in: Switzerland
In the 1940s and 1950s, the American passenger car loading gauge was increased to a 16 ft 6 in (5.03 m) height throughout most of the country outside the Northeast, to accommodate dome cars and later Superliners and other bilevel commuter trains.
Traditionally, the gauge of the national railway in Spain, now managed by Adif, is 1,668 mm (5 ft 5 + 21 ⁄ 32 in), known as Iberian gauge.This gauge (originally 1,674mm but then reduced slightly to allow interoperability with Portugal) was decided upon by a Parliamentary committee, after a report known as the Informe Subercase (named for its principal author) in 1844.

A measure of 100 by 100 varas (Spanish) is almost 7000 square meters, and is known traditionally throughout Spain and Latin America as a manzana (i.e., a "city block"). As well, lumber is still measured in Costa Rica using a system based on 4 vara, or 11 feet, for both round and square wood.
