Armored trains were used by both sides on the Eastern Front during WWII. In fact their use began at the end of WWI and was further developed between the wars in the conflicts in Eastern Europe. Both the "Reds" and "Whites" factions fighting for control of Russia used armored trains in considerable numbers during the Russian Civil War, as did Poland at the beginning stages of WWII. Once WWII began, the Germans had to catch up on their armored train proficiency to help protect reinforcements and supplies from reaching the eastern front since they were constantly harassed by local partisans. As the Red Army grew in strength and the front became more fluid, there were a number of battles and skirmishes between tanks and armored trains.
Each BP 42 train was powered by a BR 57 locomotive. Manufactured by Krupp in Essen, the rest of the armored train was made in Breslau by Linke-Hoffman. The BP 42's composition was symmetrical with the locomotive placed in the middle. Protected by some 13 tons of steel plating the ready to roll weight of the locomotive was about 90 tons. The BR 57 gave the train a top speed of 60 km/h and had a range of 360 km with two 3T16.5 tenders. Sold Out!
