While the production of the S 10 was still in its early stages, Henschel was hired to build a compound locomotive. It was hoped that this would help reduce coal consumption. The locomotive, designated S 10.1, was not based on the S 10 but was a new design. The four-cylinder compound engine was of the EN De Glehn type, meaning the outer cylinders at the rear acted on the second coupling axle and the inner cylinders on the first. The locomotives were larger and more powerful than the S 10 and, thanks to the compound engine, also more economical. Between 1911 and 1914, 135 units were built in two different series for Prussia and 17 for Alsace-Lorraine.
