The KUR ED1 class was a class of gauge steam locomotives built for the Kenya-Uganda Railway (KUR). The first batch of 23 were built by Vulcan Foundry between 1926 and 1927. These were followed by further four built in 1929; one by W. G. Bagnall and three by Hunslet Engine Company. The locomotives were all entered service on the KUR between 1926 and 1930. They were later operated by the KUR's successor, the East African Railways (EAR), and reclassified as part of the EAR 11 class, renumbered 1105-1131.
In 1930, four similar locomotives were built by Vulcan Foundry for the Tanganyika Railway (TR) as the TR ST class. These locomotives differed from the ED1 class units only in being fitted with vacuum brake equipment instead of Westinghouse brakes and air compressor. They, too, were later operated by the EAR, and reclassified as part of the EAR's 11 class, renumbered 1101-1104.
Nia, a character in Thomas & Friends who was introduced in 2018 (Big World Big Adventures), is based on the KUR ED1 class.[1] [2] However, unlike her basis, which is narrow gauge, Nia is standard-gauge.
