As noted in Locobase 9582, Engerth locomotives did not prove sufficiently successful to overcome the complexity of their cog-driven tenders. So beginning in 1874, two of the locomotives were modified to add a third axle forward of the firebox, which required lengthening the boiler by 100 mm. This first conversion put too much weight on the third axle.
The second conversion idea showed greater promise when the railway adopted a Klose mechanism that drove the front tender axle as well as the three coupled axle. Its layout also redistributed the weight more evenly.
Of the 20 locomotives, 11 were retired in the first decade of the 20th Century. Most of the others lasted until the late 1920s and early 1930s.
