delivered 57 units (429.01–429.57) to the kkStB. In spite of the small superheater area, problems arose with the slide valve on the low-pressure side. As a result, the following 126 engines were supplied with piston valves on both sides (429.100–429.225). At the same time a two-cylinder simple variant with piston valves was tried, of which in the end 197 units were procured by the kkStB (429.900–429.999 and 429.1900–429.1996). The Austrian Southern Railway Company (''Südbahn'') procured six

The six Südbahn locomotives came to the MÁV, which gave them the designation 323.901–323.906. In addition, the ex kkStB 429.116, which had gone to the PKP as Ol12-24, went to the MÁV as 323.907, the number of which was later changed to 323.908. In 1939 the

in Czechoslovakia converted all its compound locomotives (27 of the first series, 57 of the second) into two-cylinder engines. Together with the 68 two-cylinder machines taken over, they therefore had over 152 examples of Class 354.7. With the exception of one engine, all the locomotives were give a second steam dome with a connecting pipe. The ČSD did not withdraw Class 354.7 engines from its fleet until 1967.
