Based on the development of the VT 41 class diesel railcars, the Austrian Federal Railways (ÖBB) acquired larger VT 42 class diesel railcars between 1935 and 1937. These vehicles were equipped with two 210 hp motors designed for a maximum speed of 110 km/h. After World War II, the ÖBB reclassified the railcars under the new series designation 5042. Until their electrification, they were used on the "Westbahn" railway lines, operating in express trains among other services. Following electrification, their main areas of operation then shifted to Villach, Graz, and Lienz, though they continued to serve in fast and express trains.
