In 1895 the Royal Württemberg State Railways ordered a steam railcar using a Serpollet boiler from Esslingen, followed by six more. At first, their performance was unsatisfactory, until Eugen Kittel of the Württemberg State Railways developed a new firebox. Seventeen were built for the Württemberg State Railways and railcars were also made for the Royal Saxon State Railways, Swiss Northeastern Railway and Imperial Royal Austrian State Railways, and the Grand Duchy of Baden State Railway in 1914–15.
