Schöma
Schöma is a company based in Diepholz, Germany, specialising in the construction of small diesel locomotives. After Christoph Schöttler left his father's business, the Diepholzer Maschinenfabrik Fritz Schöttler (DIEMA), because of disagreements about the product range, in 1930 he founded his own machine factory, the Christoph Schöttler Maschinenfabrik GmbH, on the former premises of DIEMA. The company was first called SCHÖMAG for short, which was changed a few years later to Schöma.
