They went straight for an axle arrangement of 1' D, missing out a locomotive with a simple D arrangement. Twelve examples of this variant were manufactured by Krauss. The cylinders were located in front of the carrying axle and drove the first coupled wheels. The next two driving axles were housed in a Krauss-Helmholtz bogie. In addition the external Walschaerts valve gear, with its very short connecting rods, was a peculiarly Bavarian version.

The vehicles were issued with a Bavarian 2'2' T 18 tender. Later they were given class 3 T 12,3 tenders from the Bavarian B XI.

It had two overlapping cylinders that formed a combined double slide valve ("Doppelschieber"). The carrying axle and the first driving axle were housed in a Krauss-Helmholtz bogie. The advantage of this locomotive variant was that the double cylinder was very short as a result of the tandem construction. That said, the engine did not perform especially well, so that the two units were converted into locomotives with a conventional cylinder arrangement.

A total of 48 vehicles were made and 42 were taken over by the Reichsbahn with the numbers 56 312 - 56 353. It was the same as the "Sondermann variant" after the conversion of the latter. These locomotives could haul a train of 820 tons at a speed of 50 km/h and even attained a speed of 40 km/h with a 1,390 ton train. On a line with a 0.5% incline they could manage a 845 ton train at 25 km/h.

The two machines were the first in Germany to have a sectional frame, which had been standard in the USA virtually from the beginning and which had been developed from the wooden beam frames of the early locomotives.

Like the two S 2/5 express train locomotives also imported from Baldwin a year later these engines were equipped with a four-cylinder Vauclain compound engine, on which the high-pressure and low-pressure cylinders were located directly one above the other and worked on the same connecting rods. Apart from the sectional frame, this type of drive did not catch on in Bavaria.

The locomotives were equipped with Bavarian 2'2' T 18,1 tenders.
