A railway employee in conversation with another man. The former presents two instruments used to test locomotives (test bench, measuring car). When asked, he emphatically explains that despite modern machines, people are indispensable for the operation of the Reichsbahn. The film then shows various Reichsbahn employees at their workplaces, engaged in staged dialogues with each other and with railway customers. Locomotive drivers and stokers, conductors, shunters at a station, signal box employees, and track workers are shown. Finally, railway workers are seen in their free time and socializing at a colleague's birthday party.
