Deutsche Bundesbahn 2-10-2 Locomotives in Germany

Class BR 45 - umbau (Locobase 20621)

Data from "Baureihe 45 Umbau [Deutsches Bundesbahn]", Albert Gieseler's Dampfmaschinen und Lokomotiven website at [], last accessed 9 August 2019. Works numbers were 24796-24821 in 1940-1941.

As noted in Locobase 4318, the big Santa Fes that entered service on the Deutches Reichsbahn in the late 1930s were designed to put as much power as possible on a 19 metric ton axle loading. A new steel (St 47) lightened the boiler considerably, but it proved too susceptible to fatigue.

This set of ten was part of the 27 that remained in West Germany after the Third Reich's defeat in 1945; only one BR 45 went to the East German DRG.

The reorganized Bundesbahn contracted with Krupp to produce new boilers. Five of them--45 008-009, 012, 014, and 022--are described as fitted with "neukessel erheilten" that is, a design that used a combustion chamber. A new arrangement of shorter tubes and flues featured more of both, but of smaller diameters than the originals.

The other five received Stehlkessels---welded boilers. All received underfeed mechanical stokers.

The ten rebuilt locomotives earned a reputation as prodigious haulers But four of those with a combustion chamber were retired in 1957. Only 012 lingered into the 1960s.
