This compound Mogul design was fitted with the Krauss-Helmholz truck that combines the first driving axle with the pony truck. The relatively high boiler pressure and cylinder volume generated considerable power. These engines were rated at 590 tons on the level reaching a speed of 60 km/h (37 mph) and 210 tons up a 1/2% grade at 25 km/h (16 mph). Krauss delivered the first 83 beginning in 1899 and Krauss and Maffei added 37 more in 1907 as class G 3/4 N. (See Locobase 5934).
When the DRG was formed, 64 of the class were grouped as 54 1301-1364. This contingent began retiring in 1931.

Although based on the G 3/4 N compounds, this class -- built by Krauss and Maffei -- had a larger, higher-pitched boiler and a longer rigid wheelbase. The first superheated Moguls in service, these locomotives proved economical and efficient. This first set of 155 had separate steam and sand domes. (See Locobase 5936 for the follow-ons, which had a single dome.) Additional data from US Military Railway Service Equipment Data Book -- German Locomotives supplied by Allen Stanley from his extensive Rail Data Exchange in March 2004.
Obviously satisfactory, the class lasted through most of Germany's steam era, the last being retired at Nuremburg in 1966.

This was the later batch of 70 superheated Moguls to round out the class begun in 1919. Krauss and Maffei split the production order. The principal difference between the two classes, other than a slight increase in adhesion weight, was the combination of steam and sand dome under a single casing.
Like the others, these locomotives were long-lived.
Christian Lindecke's website [] (visited 28 Nov 2003) (translated by Google), supplemented by [] . Lindecke says these were duplicates of the 1899 C VI-class Moguls with only a slight increase in weight.
Thirty-two were still in service when the DRG took over the class and they were number 53 1401-53 1432. The last was withdrawn in 1932.
