The steam locomotive class kkStB 429 was a class of passenger locomotive operated by the Imperial Royal Austrian State Railways (Kaiserlich-königliche österreichische Staatsbahnen), kkStB.
As Wilhelm Schmidt's superheater went into series production, Karl Gölsdorf modified the Class 329 into the superheated variant 429. The smokebox was lengthened, the boiler barrel reduced accordingly, high-pressure cylinder was given piston valves, the low-pressure cylinder slide valves. The Lokomotivfabrik Floridsdorf, the Wiener Neustädter Lokomotivfabrik and the Lokomotivfabrik der StEG 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).
