Service history
- The pair pulled the opening KFNB train from Floridsdorf to Deutsch-Wagram.
- They soon struggled with rising traffic and were transferred to the Stockerau line.
- After a serious Versailles accident on May 8, 1842, two-axle locomotives were banned in Austria.
- The locomotives were withdrawn, stored in 1846, struck off in 1849, and scrapped in 1849 or 1852 after plans to convert them to 2-2-2 with an extra carrying axle did not go ahead.
