Technical Details


Nia is based on the KUR ED1 class, a class of 2-6-2 tank locomotive built by Vulcan Foundry for the Kenya-Uganda Railway between 1926 and 1930. They were later operated by the East African Railways and were reclassified as part of the EAR 11 class.

Nia has been modified in order to work on British railways. Whereas her original basis was narrow gauge, Nia is standard gauge, and she has been given buffers and screw link couplings in order to work with the other engines.


Nia is painted orange with yellow lining. She has yellow, green and red patterns painted along her tanks, dome and cylinders, and her footplate is painted red.
