Panzer IV on a Rail Wagon

A lone Panzerkampfwagen IV Ausf.C sits on a platform wagon at a rail-head. The panzer is identifiable as an Ausf.C by the arrangement of the view ports on superstructure front. Note also that the cupola differs from that of the Ausf.A. There are no markings visible, while crew members wear the black M1934 panzer uniform, along with the caracteristic large black beret. Typically, the Germans did not chain tracked vehicles to rail wagons, preferring instead to use wooden blocks and chocks to prevent fore-to-aft and side-to-side movement.
