The many new lines brought into service on the Prussian whole of the networks and EL, at the end of the last century, are planned for the circulation of a generation of hardware admitting 15 tons per axle. The moment thus had just thought of the replacement of excellent classes G3 and G4 by a machine at the same time more powerful and more rapid. In 1892, Vulkan with Stettin proposes one 130 having, because of the standardization, the aspect of very large G4 with front bissel. During years of production, it will evolve/move appreciably; the most significant differences in aspect come from the right apron, of the cabin to the front cross-piece for the machines with drawers and internal distribution, apron in several aliasings for those with drawers and external distribution Heusinger. The EL constitutes an extremely significant park of G5 in which all the versions are present. Thanks to the unification of the components of the machine, the customer can indeed control his engines with the card: engine with simple expansion two cylinders for broken lines and stops frequent, driving compound with two cylinders for large courses to mitigate some, internal or external distribution, hollow axle Adams for bissel or even bogie-bissel Krauss-Helmholtz for the very sinuous lines. It is the same for the unified tenders proposing variable capacities. On the few 2000 specimens resulting from ten German manufacturers, Graffenstaden are easily identifiable with the convex dome cap, that of the other firms being punts.
