Class Details by Steve Llanso of Sweat House Media

Class Ct (Locobase 1306)

Data from A E Durrant, Locomotives of Eastern Europe (New York: Augustus M Kelley, Publishers, 1966), pp. 147, 150. (Thanks to Wes Barris for his 9 November 2021 noting the complete absence of information in the original entry.)

Chrzanow supplied the first three in 1933 (works numbers were 590-592 in 1934), Henschel the other fourteen (works numbers were 23085-23088 in 1936, 25292-25294 in 1940. (Seven additional engines--works numbers 25295-25301--were not delivered owing to the Soviet occupation of Latvia in 1940.)
