and here you have "Beautiful Helen" - Polish construction still working as a turist train (right)
Left there is PM36-1
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.
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.
