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.); and Annex B--Steam Locomotives of 1435 mm gauge, Steam Locomotives of the Lithuanian Railways 1919-1914, supplied through email to Locobase. See also "Estonia and Lithuania--Rail Travel in Two Northern Republics", Railway Wonders of the World, Volume 2 (8 November 1935), archived on the RWWotW website at []. Works numbers 751-754 in 1932.
Good-sized suburban tanks supplied by a renowned Czech builder. Railway Wonders noted that these engines were "not dissimilar to the once-famous 2-4-4 tank engines built by Krauss and Company of Munich for the old Bavarian State Railways. Naturally the Lithuanian engines are more modern in every way, and greatly surpass the old Bavarian type in boiler power and general efficiency."
Although resembing in most respects to most European suburban tanks, the Tk's smoke lifters, tank sides, cab sides, and bunker sides seemed (but were not) made of a single sheet. On top of the boiler, three small equal-sized domes held sand ahead and behind the steam dome.
