Use case / Anwendungsfall

ETCS track net

Description / Beschreibung

ETCS track net covers the requirements for access and use of the rail network of the infrastructure manager in microscopic way. It provides all the technical and operational information that is necessary for entities entitled to access the network, determine train positions and generate a movement authority for the train.

On an ETCS equipped railway line, the onboard ATPs are controlled by Movement Authority (MA) messages from a wayside RBC or LEU. These messages contain detailed information about certain aspects of the infrastructure, e.g. balises, speed restrictions, gradients and track conditions. This use case aims at modelling all infrastructure data necessary for generating MAs, as defined by SUBSET-026, version 3.x.

Data Flows and Interfaces / Datenflüsse und Schnittstellen

Transfer of railway infrastructure data into the Radio Block Centre (external link, 🇩🇪, visited on 2018-04-23; RBC on Wikipedia)

In this article there is information missing with respect to the data flows. Please help improving the railML® wiki by filling the gaps. Possibly, you will find further details on the discussion page. Ferri Leberl (talk) 17:53, 10 April 2018 (CEST)
