The ''[[Rekolok]]omotives'' of '''DR Class 52.80''' first appeared in 1960 in service with the [[Deutsche Reichsbahn (GDR)|Deutsche Reichsbahn]] in [[East Germany]] as extensive rebuilds of the wartime locomotives or ''[[Kriegslokomotive]]n'' of the [[DRB Class 52]] built by [[Nazi Germany]]. This modernisation, described as 'reconstruction' (''Rekonstruktion'', hence ''Rekolokomotive''), extended to almost all of the components and systems on the engine.

==Overview==
This reconstruction should not 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 (locomotive)|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, [[Firebox (steam engine)#Combustion chamber|combustion-chambered]] [[boiler]], originally designed for the Class 50.35. Other notable features of the ''Rekolok'' were new, welded [[cylinder (locomotive)|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 valve]]s and cylinder safety valves installed on some locomotives at [[Dampflokwerk Meiningen|''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 [[Adolph Giesl-Gieslingen|Giesl-Gieslingen]] suction draught systems, the so-called [[Giesl ejector]]s. However, for licensing reasons, these were removed once they had worn out or become defective.

==Surviving locomotives==
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 [[Switzerland|Swiss]] company [[Dampflokomotiv- und Maschinenfabrik DLM]] AG in 1998.<ref name="eri-2004-301">{{cite journal| first=Roger M.| last=Waller| title=Die Modernisierung der Dampflokomotive 52 8055| journal=[[Eisenbahn-Revue International]]| publisher=Heft| date=July 2004| issn=1421-2811| pages=301–305| language=German}}</ref> Since 2003 it is owned by its rebuilder DLM AG and based in [[Schaffhausen]], Switzerland. Being equipped with automatic trainstop of both [[Integra-Signum|Signum]] and [[European Train Control System#Limited Supervision|ETCS-LS]] type it is fully certified for operation on the Swiss [[standard gauge]] network. Number 52 8055 also have an unknown 5 chime steam whistle & a Crosby 3 chime whistle that was usually used on The [[LNER Class A4]]s.
