Young female locomotive crew on the 2-10-0 freight train steamlocomotive 52 # 8168 of the Bavarian Railway Museum (BEM) in Nördlingen. The red shield with the words: "Lok in persönlicher Pflege" /"locomotive in personal care" was placed on some steamlocomotives in the German Democratic Republic (GDR). The Soviet locomotive driver Nikolai Alexandrovich Lunin, born in 1915, had the idea of extending the service life between two main inspections between 100,000 and 200,000 kilometers by personal care of the locomotive by the personnel.
In the GDR, this idea was put into practice and such locomotives were visibly marked from the outside with a so-called Lunin pennant, a triangular sheet of metal. The 52 # 8168 is a former "GDR locomotive" and ran for the Deutsche Reichsbahn (DR).
