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".

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 corresponding code list (link to the railML^® website).

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 corresponding code list (link to the railML^® website).
