Data from "'Baltic' Type Tank Locomotive For China", Locomotive Magazine, Volume 31, No 389 (15 January 1925), pp. 5-6. See also "The Kowloon-China Railway", Railway Magazine, Volume 58, pp. 437-440. Works numbers were 5375-5378 in 1925.
LM's photograph of this passenger class confirms an initial impression that this is a big locomotive, even though, said the report, the picture didn't give "an entirely adequate idea of the size of this engine, which is ...in fact one of the largest of this particular arrangement ever constructed in Great Britain. The journal noted that the "very populous" district generated a "considerable freight and passenger traffic.".
A relatively large Belpaire firebox contained a moderately sized grate.The quartet operated on the K-C railway until the Japanese overran Hong Kong in early 1942. War took a toll as only one of the 4-6-4Ts could be found when the British regained control in 1946.
