DR series 13.18
The Deutsche Reichsbahn has designated two types of locomotives of the former Grand Ducal Oldenburg State Railways with the 13.18 series :
- 13 1801 to 13 1806: see Oldenburgische S 3
- 13 1851 to 13 1861: see Oldenburgische S 5
The locomotives, both type 2'B n2v tender locomotives , were taken over by the Reichsbahn when it was founded in 1920. They were given their Reichsbahn numbering in accordance with the DR's re-drawing plan in 1925. They were retired shortly after the re-drawing by 1927.
