The five vehicles of type III a of the Grand Ducal Baden State Railways were steam locomotives that were originally built for 1600 mm broad gauge .

With the further expansion of the route network in the Rhine Valley, more locomotives were also required. A performance and consumption program was drawn up by the state railway. The delivery orders were ultimately awarded to Kessler and Maschinenfabrik Meyer . The vehicles of the latter were classified in category III b . Both companies worked together during construction, so that the locomotives differed only slightly.

The locomotives were based on the construction of the EXPANSION of type Ib . With the large driving wheels of 1.83 m a high speed could be achieved. However, the pulling power turned out to be too low. When starting up the 1: 250 slope near Ettlingen , six to eight men had to be pushed.

The locomotives were equipped with double inner frames , inner cylinders, Sharp kettles and a semicircular standing kettle . In addition, a Meyer expansion control with double rails and a fork control for the basic slide was used. In 1846 the MURG received a Stephenson control. Like all locomotives in Baden at the time, the vehicles were converted to standard gauge in 1854 and remained in service until the 1860s. During the conversion, the nameplates of the MURG , KINZIG and NECKAR locomotives were swapped.

The vehicles had a Tender of type 3 T 5.40.
