Data from E L Ahrons, "Locomotives of the Egyptian State Railways", Locomotive Magazine, Volume XXV [25]. (15 September 1919), pp. 157-160. Works numbers were 5439-5440 in 1911.
The DLR bought this pair of driver-leading passenger tanks to join the 2-4-2Ts. Like those locomotives, these had Belpaire fireboxes.
