Data from "Rogers Mogul for China", Locomotive Engineering, Volume X [10], No 1 (January 1898), p.57 and 'Rogers Moguls for the Imperial Government Railways", Railway Review (4 December 1897). See also Charles Denby and E P Allen, "Chinese Railroad Development, Past, Present, and Future", The Engineering Magazine, Volume XVI, No 3 (December 1898), pp. 339-348, esp 343. Works numbers were 5218-5219 in October 1897, 5220-5225 in November.
Very much a North American Mogul of the time, this engine had a Belpaire firebox and relatively large dimensions for such duty. A visual difference was the use of a clerestory cab.
Financing went through Fearon Daniel & Company for Hong Kong & Shanghai Banking Company for the Belgian syndicate (possibly a "stalking-horse" for Russian interests, said Denby and Allen) building the Lu Han road between Hankow and Canton in southern China. At the time of writing in 1898, 30 miles at the Peking end of the line had been completed with further road bed construction; Hankow was 700 miles south of Peking and Canton lay 700 mile further south.. The Moguls had arrived "recently ...near the scene of operations, and are awaiting the completion of additional road before being put in service."
