Ausgangsmaßen

Ausgangsmaßen is a term used in German and Austrian rail networks to designate the starting point or initial station of a railway journey. The concept is essential to understand the workings of the Deutsche Bahn, the national railway company of Germany, and ÖBB, the Austrian Federal Railways.

In a departure-line (Abfahrt), trains start from their Ausgangsmaß as a reference point for their departure and journey. The designation of the Ausgangsmaß is specific to each train line and service, and each locomotive and passenger train is equipped to accurately determine its precise starting point. From there, trains follow the correct departure path guided by technical installations and visual signs.

The Ausgangsmaß is typically defined by a section of rail track and is distinguished from the departure point itself, which marks the exact spot where the train begins to move. For instance, on a bi-directional line, where a train might depart from both ends, different Ausgangsmaße are designated accordingly, even if the departure points might appear the same.

The main purpose of the Ausgangsmaß is to provide trains with a specific reference point for navigation and to maintain safety, especially in situations involving maneuvering or track work. The Ausgangsmaß plays a significant role in ensuring that trains can operate safely and efficiently on the railways.
