In a nineteenth century context, traffic could mean both communication and the transportation of goods and people. For instance, the German term “traffic” (Verkehr), referred to “communicating” (verkehren) and to “traffic”/“transportation” (Verkehr). Historically speaking, before the age of telegraphy, any communication over distance required the physical transport of a message or a messenger. Many authors, thus, identified the latter as a fundamental caesura in the relationship between media and mobility, uncoupling media from their previous reliance on physical movement. At the same time, telegraphy and the railway formed a paradigmatic symbiosis that enforced the ongoing duality between media and mobility: traffic depended on and sometimes boosted communication and vice versa. Hence, traffic and media were not disconnected as such, but their connections were rearranged and new ones emerged while others such as the postal services persisted.
