The Railway Regulation (Gauge) Act was enacted by the United Kingdom Parliament on 18 August 1846. It mandated standard gauges of 4 ft 8 1⁄2 in (1,435 mm) for Great Britain, and 5 ft 3 in (1,600 mm) for Ireland. The 7 ft (2,134 mm) gauge, designed by Isambard Kingdom Brunel when engineering the Great Western Railway, was limited to the south west of England and Wales. The law stated that these railways "shall be constructed on the Gauge of Seven Feet". This isolation ultimately marked the end for Brunel's 7 ft broad gauge system.
