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.

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.

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.

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.

Being equipped with automatic trainstop of both Signum and ETCS-LS type it is fully certified for operation on the Swiss standard gauge network.
