Dev:Border between infrastructure managers and countries

Introduction

Border between infrastructure managers (handover point) is the point where legal responsibility changes between the infrastructure managers (IM) [TAF TAP TSI].

These IM borders can be found between countries and within one e.g. in case there are private and national railway infrastructure managers in a country. Sometimes there two railway lines meet each other. Therefore below you can see two examples:

• border between lines and border between IMs coincide;
• border between IMs is within one line.

Borders between IMs and railway lines coincide

The photo shows an example of a ‘handover point’ between Germany and Austria, IMs DB InfraGO ( 🇩🇪) in Germany and ÖBB Infra () in Austria. Here also two railway lines meet each other - "Bahnstrecke München Ost Pbf – Simbach (Inn) (DB-Grenze)" and "Bahnstrecke Neumarkt-Kallham – Staatsgrenze nächst Braunau am Inn". Mileage of the border was obtained from Variabler Infrastruktur Aggregator.

In the source code, shown below, there are two tracks. When choosing approach with two tracks be aware of semantic constraints e.g. IS:003 "If two <track>s are connected, the @absPos values of the connected <trackBegin> and <trackEnd> must be identical" . Here exception to restriction IS:003 applies because tracks belong to different mileage systems. In code this justification is represented via two railway lines referring to tracks.

Ownership is represented by @infrastructureManagerRef of <line> elements. Further information about IMs is given in the <infrastructureManager> element and the corresponding code list.

Border between IMs is within one railway line

The photo shows an example of a ‘handover point’ at the Germany-Czech Republic border on Děčín–Dresden-Neustadt_railway (). This line is operated by two different rail operating companies, Správa_železnic () in the Czech Republic and DB InfraGO ( 🇩🇪) in Germany, meaning there is a change in infrastructure managers. Mileage of the border was obtained from Variabler Infrastruktur Aggregator.

In the source code, shown below, there is one track. Ownership is represented by <ownerChange> elements. Further information about IMs is given in the <infrastructureManager> element and in the corresponding code list.
