Southern Railway Company ordered a tank locomotive for heavy passenger train service as a replacement for the 229 series locomotives that had become too weak. The locomotive factory of the State Railway Company then developed the superheated steam type of the 629 series as the first tank locomotive in the world with the Pacific wheel arrangement 2'C1'. The first 629 was delivered to the Southern Railway Company in 1913, and 14 more in a total of 3 delivery series followed in the next two years. The extraordinarily positive experience with this series prompted the Imperial-Royal State Railways to purchase 25 almost identical locomotives by the end of the monarchy in 1918. Fifteen Southern Railway machines and ten State Railway units remained in Austria after the First World War. 15 units had to be handed over to the newly founded CSD, which designated them as 354.121 to 135.
