Summary edit
| Description | DR (ex-DRG) Class "41" "Rekolok" 2-8-2 No.41 1144 (ex-41 144), with 2'2'T34 tender at the Meingen Steam Festival, 09/12. The DRG/DRB built 366 Class 41's for express freight traffic 1937-41 with boilers using the new, advanced, high tensile, St47K-Mo steel enabling the high boiler pressure of 284 p.s.i. to be used. However, the steel proved very prone to metal fatigue and extensive cracking resulted. As a result, the pressure was reduced to 255 p.s.i. in 1941 as a temporay expedient during the war. After World War II, 216 were in West Germany (DB), 122 in the East (DR), 26 in Poland (PKP Class Ot-1), 1 in Czechoslavakia (CSD) and 1 had been destroyed. After temporary repairs in the early 1950's, the DB completely rebuilt 107 in 1957-61 with all welded boilers with combustion chambers, wide chimneys, and a platform replacing the front fall plate. In 1968-70 40 were converted to burn oil and reclassified "042", the remaining coal burmers being Class "041". The last "042" was withdrawn at Rheine in 1977. On the DR, 10 of their "41's" were in such bad condition that they were withdrawn immediately, whilst 33 were fitted with a "1943 Type" boiler of conventional steel and were safe. The 79 others had extensive welding repairs on their St47K boilers but this made them even more prone to cracking so many were temporarily withdrawn. Then in 1958, 03 1046's St47K's boiler exploded so an urgent reboilering programme was instituted. 102 were to be fitted with a new, high performance "39E Reko" all-welded boiler with combustion chamber, IfS feed water heater,Troffimoff piston valves, Stuhren ash pans and new welded front cabs. They proved excellent steamers (the boiler generating 15 tons of steam an hour compared to 13.3 tons an hour for the DB's contemporary all-welded boiler of similar size on their Class "41's"). So exceptional was the performance of the DR Class "41" Rekoloks, that they were frequently used on express and semi-fast passenger as well as fast freight. The last DR loco was withdrawn in 1988. | |||||||||||||
