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

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

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
