The heavy [[BBÖ 214|Class 214]] 1’D2′ (2–8–4) two-cylinder simple expansion express passenger locomotive was developed in Austria in 1927. It was designed by engineers of the [[Lokomotivfabrik Floridsdorf|Floridsdorf Werke]] and was the largest Austrian steam locomotive and the most powerful Berkshire type to run in Europe. Designed for the [[West railway (Austria)|West railway]] express train service, they were to be used to haul 580-ton express trains from [[Wien Westbahnhof]] in [[Vienna]] over {{convert|317|km|mi|abbr=off}} to [[Salzburg]]. This mainline has three approximately {{convert|11.3|km|mi|adj=mid|long|0|abbr=off}} banks with gradients between 1 in 91 and 1 in 125.

Two prototypes were built, a two-cylinder and three-cylinder version. When tested, the two-cylinder version proved to be superior to the three-cylinder [[BBÖ 114|Class 114]] version, and eventually twelve more two-cylinder Class 214 locomotives were built. In 1936, No. 214.13 reached a speed of {{convert|156|km/h|mph|abbr=off}}, the highest speed ever attained by an Austrian steam locomotive. The regular speed limit was {{convert|120|km/h|mph|abbr=off}}.

From 1938, the [[Deutsche Reichsbahn]] (DRB) designated the locomotive class 12.0. In the mid-1939, they hauled 600 tons express trains out of Vienna over [[Vienna Woods|Wienerwald]] at a speed of {{convert|65|km/h|mph|abbr=off}}, reaching {{convert|120|km/h|mph|abbr=off}} over level stretches.

In 1945, seven of these locomotives were taken over by the [[Soviet Military Administration in Germany|Soviet Military Administration]] when they occupied the [[Allied-occupied Austria|Russian Zone in Austria]]. These locomotives had "''T''" (Trofya) painted before their running numbers and were marked "CCCP". The Russians did not transfer these locomotives out of Austria and, when they withdrew their occupying forces in September 1955, the locomotives were returned to the [[Austrian Federal Railways]] (ÖBB).

When the mainline west of Vienna was electrified, all the ÖBB 1’D2’ locomotives were taken out of service and written off. On 15 February 1962, locomotive No. 12.10, built by Floridsdorf in 1936, was preserved as museum locomotive at the Eisenbahnmuseum Strasshof.
