In 1929 the First Locomotive Factory in Poland (Fablok) designed a W5A type locomotive, basing upon its earlier W2A type (PKP
Tx26-427), and manufactured two units (later designated
PKP class Px27). In 1938 another one slightly differing locomotive was ordered by
Września County Railway (
Wrzesińska Kolej Powiatowa), later to become Px38 class. It was a D () locomotive with a two-axle tender. It was powered by a simple twin engine, working on a saturated steam, developing 110 hp power output. It has been active, as of 2015. In 2015 it left Poland for the first time, taking part in narrow gauge railway meetings in Germany and
Pithiviers in France. ==References==
