In common with the Krauss engines the ML 2/2 had the

on the inside.

In 1906 Maffei delivered the first three locomotives (railway numbers 4001–4003). In spite of the unusual, and for a two-cylinder locomotive, extremely complicated gear system, the engines proved themselves, and Maffei supplied another 21 examples up to 1908 (Nos. 4004–4024). The positive experience with these locomotives also led to the construction of the Class MCCi steam railbus, whose driven bogie and boiler were very similar to those of the ML 2/2.

Three locomotives were sold to the United Fireclay Factories (Vereinigten Schamottefabriken) in

in 1923 as 98 361-384. However, they were retired by 1924. The reason was the complicated and maintenance-intensive driving gear.
