Durchläufer

Durchläufer is a German term whose meaning varies by context, derived from durch (through) and Läufer (runner). Literally, it denotes something that runs through or continues through a process, route, or system.

In rail transport, Durchläufer is used to describe vehicles or services that operate through a network without being detached at intermediate terminals. The idea is a through-running arrangement where a coach or wagon remains in service across different routes or timetables, reducing handling and transfer needs for passengers or freight.

In manufacturing and logistics, the concept appears in the sense of items that pass through successive workstations in a production line with minimal storage between steps. Such flow-oriented handling is related to Durchlauffertigung (flow production) and is contrasted with batch processing, emphasizing continuous movement from one stage to the next.

In other contexts, the term can be employed more generally to indicate something that proceeds through a system or process. Because usage is domain-specific and regional, precise nuances may differ and in some areas alternative terms (such as Durchlauf, Durchlaufzeit, or specific railway phrases like Durchlaufwagen) are preferred for clarity.

Overall, Durchläufer captures the notion of a continuous passage through a route or process, whether in transportation, manufacturing, or more general workflows.
