How it started
Early years 1919-1939
Fablok was established in 1919. A year later a contract was signed with the Polish government to supply 1,200 steam locomotives within ten years to the Polish State Railways (PKP). The first locomotive was delivered on 7 April 1924.
In 1931, Fablok built the first diesel locomotive made in Poland, designated Fablok G1C. It was intended only for works transportation, but the locomotive was proven too weak, the next test runs occurred in 1939.
the first locomotive was exported to the Bulgarian State Railways. During 1935 and 1936, five electric locomotives were built under license from Metropolitan-Vickers. In 1935–1936, Fablok produced five Luxtorpedas (fast railcars) for PKP under the guidance of engineer Klemens Stefan Sielecki. They were based on the Austro-Daimler's design, but substantially modified.
Two experimental fast steam locomotives were built in 1937. One of them (Pm36-1) had aerodynamic fairing, the other had a standard look. The idea was to test both engines in parallel to compare top speed, acceleration, coal and water consumption, etc. The Pm36-1 won a gold medal at the International Exposition of Art and Technology in 1937.
World War II 1939-1945
