German Railway D311.01 A/B and D311.02 A/B

"Schwerer Gustav", an experimental proto-type oil-electric engine to move the DORA in 1941 became the standard by 1942

The German High Command (OKH) gave as assignment to the firm of Krupp of Essen in 1937 to develop a giant gun, which had to be able to destroy the strongest fortresses known at the time. The gun also had to be able to fire from long distances to keep it out of reach from enemy artillery. The giant DORA is considered to be the heaviest gun used in WW2. Not only to move the gun in it’s firing curve, but also to equip the various electric and hydraulic mechanisms used from hauling the ammunition to moving the gun vertically with energy, special equipment was necessary, amongst which a new railway engine was required.

As a result, Krupp developed the V188, - also called "Schwerer Gustav", a new oil-electric engine, in which the oil-electric engines had a two-fold function : to move the gun in it’s firing curve but also to move the heavy transport cars during the construction of the gun. In the firing position the V188 acted as outside power units for the giant gun. Another advantage of the engines was that they did not betray their position with smoke and steam and could be used in a rather inconspicuous way.

The Wehrmacht had planned to have 3 Dora guns built. For each one of these two engines were planned, that consisted of two parts. They had the designation D 311 and the parts were designated "A" and "B". Late in Autumn 1941 the first engines : D311.01 A/B and D311.02 A/B appeared on the gun range at Rugenwald.
