The '''kkStB 269''' was class of three [[rack railway]] [[0-12-0]] [[tank engine]]s of the [[Imperial Royal Austrian State Railways]] (''k.k. österreichische Staatsbahnen'', kkStB) designed to work on the [[Erzberg Railway]] (''Erzbergbahn'') in [[Styria]].<ref>[https://www.google.com/search?sxsrf=ALeKk00prKJ1yD2KoLCJQeScx_HdS1_9zA:1598702189448&q=Erzberg+Railway&npsic=0&rflfq=1&rlha=0&rllag=47496090,14948957,4073&tbm=lcl&ved=2ahUKEwil5-ngrcDrAhWjp1kKHSibBC4QtgN6BAgMEAQ&rldoc=1#rlfi=hd:;si:5131755678368483097,l,Cg9FcnpiZXJnIFJhaWx3YXlaGgoHcmFpbHdheSIPZXJ6YmVyZyByYWlsd2F5,y,ZEFH6Jk-CZk;mv:47.5498438,14.995191],[47.466656199999996,14.8733242 Erzberg Railway]</ref>
==History== [[File:197 301 Strasshof.jpg|thumb|left|Museum lokomotive 197.01 in the ''[[Strasshof Railway Museum]]'' in April 2000]] As early as 1911, the ''Erzbergbahn'' was no longer able to cope with operation with the 18 existing steam locomotives of the [[kkStB 69|69 series]]. Since a double-track expansion of the line was not possible, more powerful locomotives were required. On behalf of the kkStB, chief designer [[Karl Gölsdorf]] designed the class 269 rack railway steam locomotives; they were constructed by [[Lokomotivfabrik Floridsdorf]] in [[Vienna]].
The result was a six-axle tank locomotive with the axle formula Fn4zzt: six coupled driving axles in a rigid frame and a gear drive with two gear wheels. This seldom used design as a twelve-coupled could transport {{convert|150|t}} on this route at {{convert|15|km/h|mph|0|abbr=on}} and should avoid the use of [[bank engine|banker]] (pusher) locomotives. In 1912 the three new steam locomotives were put into operation and were given the designation 269.01 to 269.03. The designation [[kkStB 169|169]] was already assigned to locomotives of the kkStB on the Tannwald-Grünthal line (today in the Czech Republic). Since there was no further orders, they could not completely replace the 69 class. Until the development of the 297 series in 1941, they were the most powerful cog railway locomotives in the world.
When it was taken over by the [[Deutsche Reichsbahn]] in 1938, the locomotives were given the designation 97 301 to 97 303. From 1953, the locomotives were given the [[ÖBB]] numbers 197.301 to 197.303 in order to differentiate themselves more clearly from the previous series 97.201–97.218. In 1953 the 197 series were equipped with [[Giesl ejector]]s, a performance-enhancing chimney construction. They were retired between 1975 and 1978.
The 197.301 was handed over to the Austrian Railway Museum in an operational condition in 1979 and is currently in the [[Strasshof Railway Museum]] in Lower Austria. It has not been put back into operation since its boiler ticket expired in 2002 {{as of|2020}}.
