KUR ED1 class

The KUR ED1 class was a class of 1,000 mm (3 ft 3+3⁄8 in) gauge 2-6-2T steam locomotives built for the Kenya-Uganda Railway (KUR). The 27 members of the ED1 class 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.[1]

In 1930, four similar locomotives were built 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.[2]
