I was thinking to leave it for competition or something but hell with that

I'm going to give you today something special: very unique locomotive fast steam locomotive built in Poland.
The design of PM36 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.
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.
Nowadays, since its restoration in 1995, PM36-2 is working as a tourist attraction in Wolsztyn being called Beautiful Helen (in polish Piękna Helena).
However very rarely you can see it outiside on normal tracks, as I was able to take some photos of it.
