appearance. DR Reko locomotive 01.5 From 1962, the Reichsbahn repair shop (Reichsbahnausbesserungswerk) at Meiningen rebuilt 35 Class 01 engines for the DR under the direction of the research and trials division VES-M Halle. Like the DB, they selected only those locomotives with more powerful brakes (from 01 102). All these locos were fitted with new Witte smoke deflectors with tapered edges, a new driver's cab and a new boiler, positioned higher on the frame. The boiler had a combustion chamber, a mixer preheater and a continuous cover for the dome. Preserved locomotives Operational locomotives Only a few locomotives of the original design have been preserved unchanged over the course of time. Of the two-cylinder Class 01 engines, the following are currently operational: 01 118, built in 1934, is the only one to have been operational without interruption until today. After the war it was in service with the DR; since 1981 it has belonged to the Historic Railway, Frankfurt (Historische Eisenbahn Frankfurt). From its base in Frankfurt Osthafen it is regularly used for museum services, including on the Frankfurt Harbour Railway (Frankfurter Hafenbahn). Another operational locomotive of this class is 01 066, built in 1928 by Schwartzkopff and which was on duty with the Deutsche Reichsbahn until 1977. Thereafter it was used as a heating engine until 1989 in the VEB Genthin washing powder factory in Nauen. The Bavarian Railway Museum in Nördlingen rebuilt the partly preserved locomotive in the Meiningen Steam Locomotive Works from individual components from other locomotives, including those of other classes – and put it back in service in summer 1993. The third operational locomotive is 01 202, that is worked by the Verein Pacific 01 202 in Switzerland. This loco was last in service with the DB and had Witte smoke deflectors. It has retained its original boiler, but lost the front apron. After its retirement in 1975, the engine was rebuilt again over 20 years with great initiative and made operational again. It was given a red livery stripe on the tender at the height of the running plate. Locomotive 01 116, which was built in 1934 with factory no. 1413 by Krupp and rebuilt in 1964/65 at RAW Meiningen, runs today as 01 533 with ÖGEG in Austria. 01 150 – DB Museum locomotive in DB configuration with Witte smoke deflectors. A new DLW Meiningen boiler was installed in 2012. On 17 October
