OKf100 was the designation used for a single Czechoslovakian-built passenger steam locomotive, formerly part of the Lithuanian TK series, used by the Polish State Railways. After 1945, one member of this series ended up in Poland, classified as the only example in the OKf100 series.

The locomotive belonged to the Lithuanian TK series of passenger tank locomotives, consisting of four units, manufactured in 1932 by Škoda Works of Czechoslovakia and bearing numbers 11 to 14.[1][2] These locomotives originally ran on standard gauge tracks, but after Lithuania was annexed by the USSR in 1940, they were converted into broad-gauge units. During World War II, they found themselves in Austria, again converted into standard gauge.[citation needed]

Unit 14 (factory number 754) was delivered to Poland, being temporally numbered as PK 14 for unknown reasons.[2] During World War Two, the locomotive served in the Škirotava engine house in Latvia, and then in Vienna-Hütteldorf in Austria.[2] The unit arrived in Poland on November 15, 1948, mistakenly listed as using the Polish designation TKp14. It entered the PKP inventory under the designation OKf100-1 and was sent for repair at the Wrocław-Nadodrze workshops, but the repairs never started and was removed from the roster in 1950. The boiler was used for heating purposes in Wrocław until 1975.[2]

The steam locomotive had two external cylinders, with a front axle on a Bissel semi-truck. The locomotive was equipped with a Knorr system brake. The linked axles and the Krauss-Helmholtz two-axle rear bogie are equipped with brakes.[2] Above the boiler is a steam dome, a sandbox and a third hood to purify the feed water.[1]
