KkStB 429

what is it?

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.
