Set of two 4-axle postal coaches, type Post-m, of the Austrian Post, operated by the Austrian Federal Railways. Simmering-Graz-Pauker Werke built four-axle postal coaches for the Austrian postal administration in several construction lots. In terms of design, they corresponded to the Eurofima wagons. The wagon body and the interior design were adapted to the needs of the railway mail service. The mail was sorted on the train. The wagons could be found in passenger, fast, and express trains. But the special coaches also travelled as far as Germany, where they were used in rerouting trains in the Allgäu region.
