Seventy engines of Baden classes III and III a were rebuilt between 1881 and 1891. They were all given a new, more powerful, three-ring boiler with a larger grate area. Because this was longer than the original boilers, the frame of the Class III had to be extended (on the Class IIIa it was long enough) and a buffer beam built onto the front.

The boiler had a Belpaire firebox with a somewhat higher top surface. A larger steam dome was fitted on top of the rear boiler ring.
