[edit] History
[edit] 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.
[edit] 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.
[edit] 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). It is occasionally used in regular service, pulling trains to Poznań [1] or Leszno. [2]
