Pm36 is the name for a Polish experimental fast steam locomotive used by PKP.
History
Design
The design was ready in 1936 and the following year the first two prototypes were built. One of them (Pm36-1) had aerodynamic fairing designed by aerospace scientists from the Warsaw University of Technology, 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.
Service
Pm36-1 was damaged and later scrapped during World War II (probably in 1942), but Pm36-2 survived and worked for PKP until 1965, when it was given to the Warsaw Railway Museum. During wartime, the machine bore the German State Railways’ number 18 602.
Present day
In 1995 the machine went through a major overhaul and is now working in Wolsztyn as a tourist attraction, called Beautiful Helen (pl. Piękna Helena).
