- Scotch gauge
Scotch gauge was the name given to a RailGauge|54
rail gauge, the distance between the inner sides of the rails, that was adopted by early 19th century railways mainly in the Lanarkshirearea of Scotland. It differed from the gauge of RailGauge|4ft8in that was used on some early lines in England; and from the Standard gaugeof RailGauge|sg. Scotch gauge became obsolete in the early 1840s when Standard gauge lines began to be constructed in Scotland, and all the lines were eventually converted to Standard Gauge.
cottish railways built to Scotch gauge
A small number of early to mid 19th century passenger railways were built to Scotch gauge, they include:
; The Ardrossan and Johnstone Railway.Whishall (2nd Edition)] : Length: 10 mile (16
km).Popplewell] Authorised on 20 July 1806and opened on 6 November 1810;Awdry (1990)]

Robert Stephenson and Companybuilt a Scotch gauge locomotive, the "St. Rollox", for the Garnkirk and Glasgow Railway; which was later sold to the Paisley and Renfrew Railway.
All the lines were later relaid in Standard gauge.
Other early 19th century Scottish gauges
4ft 6½in gauge
In addition to the above lines, there were three railways, authorised between 1822 and 1835, that were built in the
Dundeearea, to a gauge of 4ft 6½in (1385 mm). They were:
Dundee and Newtyle Railway. : Length: 10½ mile (17 km).
Newtyle and Coupar Angus Railway. : Length: 6⅓ mile (10 km).
Newtyle and Glammis Railway. : Length: 10 mile (16 km).
5ft 6in gauge
Grainger and Millerbuilt another two railway lines in the same area to a gauge of RailGauge|66. Thomas Graingeris said to have chosen this gauge, since he regarded Standard gaugeas being too narrow and Isambard Kingdom Brunel's RailGauge|84 Broad Gauge as being too wide. They were:
Dundee and Arbroath Railway; : Length: 14½ mile (23 km). Incorporated on 19 May 1836and opened in part in October 1838.Awdry]
Arbroath and Forfar Railway. : Length: 15 mile (24 km). Incorporated on 19 May 1836and opened in part on 24 November 1838.Awdry]
End of Scotch gauge
Glasgow, Paisley, Kilmarnock and Ayr Railwayand the Glasgow, Paisley and Greenock Railway, which both obtained Parliamentary Approval on 15 July 1837and were later to become part of the Glasgow and South Western Railwayand the Caledonian Railway, respectively, were built to Standard Gaugefrom the start.
