The Ober-Grafendorf-Gresten local railway, also known as “Krumpe”, was a branch line of the Mariazell railway. For more efficient operation, the BBÖ ordered two small diesel locomotives from Simmering, which they delivered in 1934. In contrast to most locomotives of this size class, the power transmission was electrical, with the electrical part of the locomotives coming from the Siemens-Schuckert works. Two years later, a third locomotive was procured, which had a slightly more powerful motor.
The locomotives were mainly used to pull passenger trains. After the annexation of Austria in 1938, the three locomotives were run by the Reichsbahn as road numbers V 15 901 to 903. From 1953 they became class 2190 at ÖBB. The first two engines were retired in 1981 and 1983. The 01 was made operational again with parts of the 02 and has been running on the Ybbstalbahn since 1991. After it ran off on the mountain in 2018 and derailed, it is waiting for its repair. The 03 was decommissioned in 1969 due to its condition, but was put back into service in 1974 after being refurbished. It got a new motor in 1992, for which it is easier to obtain spare parts, and it still serves as a shunting locomotive in St. Pölten today.
