'''PKP class Pm36''' is a class of two express passenger ('''P''') [[4-6-2]] ('''m''') [[steam locomotive]]s ordered in 19'''36''' for the [[Polskie Koleje Państwowe]] (Polish State Railways).

==History==

===Design===

The design was ready in 1936, and in the following year, the first two prototypes were built. One of them, Pm36-1, had aerodynamic fairing. The construction as well as the shape of it was designed by inz. Kazimierz Zembrzuski, head of the design office in the First Polish Factory of Locomotives and at the same time professor of the [[Warsaw University of Technology]]. The other (Pm36-2) 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 1937
[[Exposition Internationale des Arts et Techniques dans la Vie Moderne (1937)|International Exposition of Art and Technology]]
in Paris.

===Service===
After the German occupation of Poland during [[World War II]], the two locomotives were renumbered into the [[Deutsche Reichsbahn]] (DRB) fleet as 18 601 and 18 602 (class 18<sup>6</sup>). The 18 601 had its streamlining removed,{{sfn|Durrant|1972|p=111}} but was later damaged and subsequently scrapped (probably in 1942). The 18 602 survived the war, and was returned to Poland where it regained its PKP class and number. It continued to work for [[Polskie Koleje Państwowe|PKP]] until 1965, when it was given to the ''[[Warsaw Railway Museum]]''.

===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]]<ref>{{cite web|url=http://rail.phototrans.eu/14,52945,0.html|title=Train no. 77333 Wolsztyn - Poznań|access-date=2011-12-30}}</ref> or [[Leszno]].<ref>{{cite web|url=http://rail.phototrans.eu/14,58536,0.html|title=Train no. 70422 Wolsztyn - Leszno|access-date=2011-12-30}}</ref> Currently, Beautiful Helena waits for repair in [[Wolsztyn]].<ref>{{cite web| url=http://tomi.holdys.pl/index2.php?desc=on&par=pm36-1| title=Pm36-1| website=Wciaz pod para...
