The seven members of the class were built during the latter stages of World War II by Beyer, Peacock & Co. in Manchester, England, for the War Department of the United Kingdom and the Kenya-Uganda Railway (KUR). They entered service on the KUR in 1944, and were later operated by the KUR's successor, the East African Railways (EAR).[2]

gollark: GPUs as good parallel processors, or a good way to market/fund parallel processors, that is.
gollark: Not really. I recall reading that Nvidia's founders explicitly thought of this.
gollark: And AI is being spun off onto dedicatedish hardware too now, it just happens that general-purpose GPUs were the best parallel processing things available for a while.
gollark: I think they have ASICs for that now?
gollark: Bitcoin is mined on ASICs, so no.
