One of the few locomotive types that the independent Lithuanian State Railways procured between the world wars was the Tk, built by Škoda. It was a four-coupled tank locomotive that had a leading axle and a bogie at the rear. The bogie ensured that the supplies could be relatively large with 4.5 m³ of coal and 12 m³ of water. With a coupling wheel diameter of 1,600 mm, speeds of up to 90 km/h could be reached. Four pieces were made, which were numbered 11 to 14.

Although tank locomotives with this wheel arrangement were mainly used in suburban traffic in other countries, the Tk was mainly used outside of the large cities and was even used in front of express trains. So they pulled the express train from Berlin to Daugavpils in Latvia for at least 143 km from border to border through the rather small country. From 1939 they were replaced in this role by the Pacific Tender Locomotives Gp. After the Second World War, both surviving pieces had to be handed over to the Soviet Union. One engine each remained in the GDR and in Poland, both of which were no longer in regular service.
