Data from WilliamBay, Danmarks Damplokomotiver (1977). Class information from []. Works numbers were 123-124 in 1874 and 141-142 in 1875.
These tanks were based on the earlier O class, but purchased from a British builder. They served the JFJ until that railway was joined with others (including the SJS) in the Danish State Railway system in 1893. They continued in shunting service until retirement and scrapping, the first (M 60) in 1923, followed by M 82 (1933), M 59 (1935), and M 83 (1937).
