Cancellation of train or trainPart (DE: Ausfall von Zügen oder Zugteilen)

Description

It shall be possible to show cancellation of a train or trainPart within one railML file without the need for the importing system to compare two files to identify cancellations.

Suggested change:

Canncellation of a train
Cancellation of a trainPart

Background

With railML 2.2 an importing system could derive cancellations by comparing two railML data sets:

Any train or trainPart missing in the second data set can be interpreted as a cancellation - e.g. train number missing in second data set.
Changes to the operationg period of the trainPart(s) can be interpreted as a cancellation - e.g. change of operationg period from Mo-Fr to Mo-Th in the second data set.

Changes in railML 2.3

A cancelled train or trainPart is written to the railML file including all regular attributes and elements. The @cancellation attribute with a value of 'true' allows the importing system to process this information accordingly - e.g. to inform passengers of a cancellation.

Compatibility 2.2 ===

The new attributes may only be used in a file for an importing system with the capability to handle cancellations. For downward compatibility the exporting system must ensure that a cancelled train or trainPart mustn't be included in the file.

railML elements

The following new attributes are available: 1. railml/timetable/trainParts/trainPart/@cancellation 1. railml/timetable/trains/train/@cancellation The following XSD file(s) have been updated: 1. timetableTypes.xsd
