The Rekolokomotives of
DR Class 52.80
DR Class 52.80 first appeared in 1960 in
service with the Deutsche Reichsbahn in
East Germany as extensive
rebuilds of the wartime locomotives or Kriegslokomotiven of DRB Class
52. This modernisation, described as 'reconstruction' (Rekonstruktion,
hence Rekolokomotive), extended to almost all of the components and
systems on the engine.

This reconstruction should not to be confused with the general repair
of a number of locomotives which was also carried out in the Stendal
Reichsbahn repair shop (
Reichsbahnausbesserungswerk or RAW) from 1959
onwards. Under that programme only the refinements omitted during
wartime were added back, and worn out components - or those which were
too small (again for wartime austerity reasons) - were replaced.
Usually only the firebox and pony trucks were replaced. These
refurbished engines retained their original numbers, however the
Rekoloks were reorganised, irrespective of their original numbers,
into sub-class 52.80.
For economic reasons the general repair programme was cut back,
nevertheless in early summer 1960 work began on the reconstruction of
Class 52 at RAW Stendal. Up to 1967, 200 locomotives were rebuilt with
a slightly modified, Typ 50E, combustion-chambered boiler, originally
designed for the Class 50.35. Other notable features of the Rekolok
were new, welded cylinders, an IfS/DR mixer-preheater system and a new
driver's cab front walls with oval windows, mainly on account of the
new boiler. The intention to replace the entire the cab and provide
the engines with new tenders did not come about. The worn out Class
2'2'T30 tub tenders were mainly given new tubs.
Other reconstruction measures included the installation of axle box
tightening wedges and the replacement of the Krauss-Helmholtz bogies.
Despite often expressed views to the contrary, the valves were not
replaced or rebuilt as part of the reconstruction. The 52.80 had
standard piston valves with Winterthur pressure equalisation and hence
poor riding qualities when running light. Not until the 1980s were
Trofimoff valves and cylinder safety valves installed on some
locomotives at RAW Meiningen. This improved the riding performance
hugely when the engines ran without a train, something which was also
noticeable in terms of savings in lubricants and fuel.
Some locomotives were also fitted with Giesl-Gieslingen suction
draught systems, the so-called Giesl ejectors. However, for licensing
reasons, these were removed once they had worn out or become
Of the originally 200 locomotives reconstructed, a large number are
still in existence in the hands of various owners in varying condition
(see List of preserved steam locomotives in Germany). At present
(August 2007) ten working examples are known of. Number 52 8055 was
extensively rebuilt, using advanced steam technology, oil firing and
roller bearings for both axles and drive by the Swiss company
Dampflokomotiv- und Maschinenfabrik DLM AG in 1998. Since 2003 it
is owned by its rebuilder DLM AG and based in Schaffhausen,
Switzerland. Being equipped with automatic trainstop of both Signum
and ETCS-LS type it is fully certified for operation on the Swiss
normal gauge network.
