OD.2 (P4.2) NIEMIECKI PAROWÓZ OSOBOWY Z 1898 R.

Od2 (another designation: P4.2 or BR 36.0-4) is a series of steam locomotives (steam locomotives), which were produced in the period 1898-1910 by the German company Henschel. The length of a single locomotive (with the tender) was 16.51 meters, and the service weight - 48 tons. The diameter of the driving wheels was 1750 mm, and the locomotive had 2'B axles. The P4.2 steam locomotives were constructed on the order of the German KPEV railway line (German Koenglich Preussische Eisenbahn Verwaltung) as a modernization of the P4.1 steam locomotives. Compared to their predecessors, they differed primarily in the type of steam engine - while the P4.1 had a twin engine, the P4.2 already had a coupled engine, thanks to which they were much cheaper to operate, and the power unit was more efficient. Rail vehicles of this type were among the most numerous used in the Second German Reich, both before the outbreak of World War I and during its course. After its completion, Poland received about 100 locomotives of this type as part of the war reparations. They served in the Polish State Railways under the designation Od2. Interestingly, many of them survived until the next world war, and 46 survived the conflict. They served on the Polish railroad until 1958!
