We found this picture online:
Our current club locomotive was in service with the Deutsche Reichsbahn at the time.
According to Mr M. Kwitniewski, he took this picture near Aschersleben in 1978/79.
We came across this picture through Julian Gier, who took over the pictures and the photographer's archive.
You can find several pictures from the old days on his Instagram page @steampower.ac.
A big thank you to Julian and Mr Kwitniewski for this.
We wish you, dear readers, a wonderful Advent season
