The Original
Class 03.10 locomotives were originally fitted with elegant streamline cladding and were supplied by the companies Borsig, Krupp
and Krauss-Maffei. This class was an extension of the well-known Class 03. The first 03.10 was made in 1939. However, due to
the Second World War, only 60 of a planned 140 units were manufactured. Following the example of the GDR National Railways
(DR), the German Federal Railways (DB) rebuilt the 3-cylinder-locomotives. After the war, 26 engines remained; by 1950 they had
shed their streamline cladding and were given a technical overhaul by the company Henschel in Kassel. Due to significant signs
of ageing in terms of the boilers' service life, Krupp manufactured welded boilers with combustion chambers for the DB's Class
03.10 engines between 1957 and 1961. The tender was built with protective caps for the coal box. Other alterations included
smooth-running wheel sets on the leading bogie and an automatic coal replenishment system. From the autumn of 1958, all the
locomotives were housed at the Hagen-Eckesey depot and operated from there. The economic miracle brought increased demand
for inter-city travel, prompting DB's use of the 03.10 to pull express trains, which demonstrated the engine's power and speed.
While in use, it was unable to shake a number of teething problems. According to reports, the superheated steam controller in
particular caused considerable problems. Finally in 1966, all remaining Class 03.10 engines were decommissioned and scrapped
soon after.
