Steam locomotive 01 0529 of the Deutsche Reichsbahn. Drive on two axles of the tender and via a cardan shaft to all three driving axles of the locomotive. The Deutsche Reichsbahn feared that due to the partly poor condition of the series 01, it would be increasingly difficult to maintain enough locomotives for the express trains. Therefore, they decided to reconstruct the 01, which also meant an increase in performance and the elimination of faults, and this was particularly successful with this series. The new welded boiler received a third safety valve. All boiler fittings were clad, the driver's cab was modernized, and the Witte deflectors at the front were angled. The "01 529" was equipped in 1964 with a combustion chamber boiler, a mixing preheater, and oil-fired main heating. Its last service location was Berlin-Schöneweide. It was retired in July 1983.
