For further information please visit the [https://www.railML.org official project website] or [http://en.wikipedia.org/wiki/RailML Wikipedia].


RailML® is not the finished development of a central group. Instead, railML grows through the joint work of the partners and is steadily being extended. We invite you to participate on this future-oriented project and to take advantage of these standardized interfaces. Our [http://forum.railml.org Forum] is meant to help coordinate the joint work of the development partners and provides an open discussion platform.
This wiki should support you in the development of railML<sup>®</sup> interfaces and inform you about the basic elements and modelling concepts of the railML<sup>®</sup> schema.


This wiki should supporting the development of railML-schemes. It allows users to create new content and edit existing articles, and setup a comprehensive knowledge database to the railML standard.
This wiki is being kept in English. At certain points information is provided additionally also in {{Deu|German}} and/or {{Fra|French}}. You are invited to contribute to this wiki and to the development of the {{rml}} schema. Please, see our guideline "''[[How_to_join,_edit_and_create_the_railML_wiki#How_to_join_the_Wiki|How to join the railML wiki]]''" to get to know the standards of railML's wiki and the procedure for getting a writer's account.

== Current {{rml}} subschemas ==


==== FAQ ====
Currently there are three subschemas for productive use: Infrastructure (IS), Timetable and Rostering (TT) and Rollingstock (RS). The Interlocking subschema (IL) is in active devellopment and can be obtained for devellopment and test purposes. Elements that do not fit into this structure are subsumed in the class Common (CO).


Some general questions about infrastructure related aspects in railML files are summarized on the following wiki-sites:
Open {{external|https://www.railML.org/en/user/subschemes.html}} for a list of the current coordinators of the respective schemas.


* [[IS:TrackConnections|Connection between tracks]]
The {{rml}} community has plans for two further subschemas:
* [[Diskussion:IS:mileageChange‎ | Remarks and open issues on mileage changes]]
*''Shift planning'': Additional to (vehicle) rosterings, there are ideas for implementing (personnel) shift planning.
*''Station asset management and properties'': A schema for station databases, asset management and properties was developed in the early 2000's but place on hold due to the very limited use cases at this time. With a focus to the upcoming {{external|http://www.era.europa.eu/Document-Register/Pages/PRM-TSI.aspx|TSI PRM}} a reopening of the development might be started depending from sectors needs.


=== Timetable and Rostering (TT) ===
=== Timetable and Rostering (TT) ===
{{main|Timetable|Timetable and Rostering}}
The [[timetable|timetable subschema]] is part of the complete [https://www.railML.org railML] schema providing a data structure in XML for the exchange of railway specific data. It is the subschema that is most widely used.


==== General Information ====
The timetable subschema is used for all data necessary to exchange any kind of timetable for operational or conceptional purposes including the following information:
* Operating Periods: The operating days for train services or rostering.
* Train Parts: The basic parts of a train with the same characteristics such as formation and operating period. The train part includes the actual information regarding the path of the train as a sequence of operation or control points togehter with the corresponding schedule information.
* Trains: One or more train parts make up a train and represent either the operational or the commercial view of the train run.
* Connections: The relevant connections/associations between trains at a particulare operaton or control point.
* Rostering: Train parts can be linked to form the circulations necessary for rostering (rolling stock schedules).


The timetable subschema is part of the complete [http://www.railml.org railML] schema providing a data structure in XML language for the exchange of railway specific data.
=== Infrastructure (IS) ===
 
{{main|Infrastructure}}
The timetable schema provides container for all data about any kind of timetables for operational or conceptional purposes. A flexible description of operating periods, which are important elements while dealing with timetables, is also included in the schema.
The railML® [[Infrastructure|Infrastructure subschema]] is focused on the description of  
 
the railway network infrastructure including all its various facets that

are needed by the data exchange applications. In particular, the railML
 
infrastructure schema contains the following information:
With the new branch of {{TT:Tag|rosterings}} it is intended to use this data schema as well for conceptional rolling stock schedules.
* Topology. The track network is described as a topological node edge model.
 
* Coordinates. All railway infrastructure elements can be located in an arbitrary 2- or 3-dimensional coordinate system, e.g. the WGS84 that is widely used by today's navigation software.
Please visit the [http://www.railml.org railML-Website] for more detailed information about the Timetable subschema or send an [mailto:coord@timetable.railml.org email] to the coordinator of the subschema.
* Geometry. The track geometry can be described in terms of radius and gradient.
 
* Railway infrastructure elements enclose a variety of railway relevant assets that can be found on, under, over or next to the railway track, e.g. balises, platform edges and level crossings.
==== Documentation ====
* Further located elements encompass elements that are closely linked with the railway infrastructure, but that "cannot be touched", e.g. speed profiles and track conditions.
 
The following lists provide links to Timetable Documentation sites:
 
* [[:Category:Timetable_Elements | Timetable Elements]]

It is intended to use this data schema for vehicle management as well as for detailed run-time calculations. Depending on the purpose only the {{RS:Tag|vehicles}} branch of the data tree may be populated or the {{RS:Tag|formations}} branch appears or both of them. The {{RS:Tag|vehicles}} branch contains all data related to single vehicles. However, there are data, which are mainly used in relation to a composition of vehicles. Therefore the {{RS:Tag|formations}} branch is used to reflect the characteristics an entire train or a composition of vehicles within a train.


The Rollingstock schema comprises the following features:

Current railML® subschemas

Currently there are three subschemas for productive use: Infrastructure (IS), Timetable and Rostering (TT) and Rollingstock (RS). The Interlocking subschema (IL) is in active devellopment and can be obtained for devellopment and test purposes. Elements that do not fit into this structure are subsumed in the class Common (CO).

Open https://www.railML.org/en/user/subschemes.html (external link) for a list of the current coordinators of the respective schemas.

The railML® community has plans for two further subschemas:

  • Shift planning: Additional to (vehicle) rosterings, there are ideas for implementing (personnel) shift planning.
  • Station asset management and properties: A schema for station databases, asset management and properties was developed in the early 2000's but place on hold due to the very limited use cases at this time. With a focus to the upcoming TSI PRM (external link) a reopening of the development might be started depending from sectors needs.

Timetable and Rostering (TT)

→Main Article: Timetable and Rostering

The timetable subschema is part of the complete railML schema providing a data structure in XML for the exchange of railway specific data. It is the subschema that is most widely used.

The timetable subschema is used for all data necessary to exchange any kind of timetable for operational or conceptional purposes including the following information:

  • Operating Periods: The operating days for train services or rostering.
  • Train Parts: The basic parts of a train with the same characteristics such as formation and operating period. The train part includes the actual information regarding the path of the train as a sequence of operation or control points togehter with the corresponding schedule information.
  • Trains: One or more train parts make up a train and represent either the operational or the commercial view of the train run.
  • Connections: The relevant connections/associations between trains at a particulare operaton or control point.
  • Rostering: Train parts can be linked to form the circulations necessary for rostering (rolling stock schedules).

Infrastructure (IS)

→Main Article: Infrastructure

The railML® Infrastructure subschema is focused on the description of the railway network infrastructure including all its various facets that are needed by the data exchange applications. In particular, the railML infrastructure schema contains the following information:

  • Topology. The track network is described as a topological node edge model.
  • Coordinates. All railway infrastructure elements can be located in an arbitrary 2- or 3-dimensional coordinate system, e.g. the WGS84 that is widely used by today's navigation software.
  • Geometry. The track geometry can be described in terms of radius and gradient.
  • Railway infrastructure elements enclose a variety of railway relevant assets that can be found on, under, over or next to the railway track, e.g. balises, platform edges and level crossings.
  • Further located elements encompass elements that are closely linked with the railway infrastructure, but that "cannot be touched", e.g. speed profiles and track conditions.

Rollingstock (RS)

→Main Article: Rollingstock

The rollingstock subschema is part of the complete railML schema providing a data structure in XML language for the exchange of railway specific data.

The rollingstock schema provides container for all data about any kind of rail vehicles including locomotives, multiple units, passenger and freight wagons. The second part of the schema enables the combination of single vehicles to formations as a fixed composition within a train or an entire train. It is intended to use this data schema for vehicle management as well as for detailed run-time calculations.

The Rollingstock schema comprises the following features:

  • separate parts for vehicles and for train parts or complete trains
  • possible specification of vehicle families and individual vehicles using the common features of the family
  • different level of detail for data
  1. vehicle as black box (with respect to dynamic characteristics) with only mean values
  2. vehicle as black box (with respect to dynamic characteristics) with curves for particular values being variable within the operating range
  3. vehicle as white box with details about the internal propulsion system
  • vehicles with motive power, for passenger or freight use
  • combination of vehicles to formations, i.e. train parts or complete trains

Interlocking (IL)

→Main Article: Interlocking

The interlocking subschema will focus on information that infrastructure managers and signal manufacturing industry typically maintain in signal plans and route locking tables:

  • Data transfer: a standard data exchange format will allow the automation of data transfer, which is the process of adapting a railway interlocking and signalling system to a specific yard.
  • Simulation programs: the railML® IL schema allows modellers to quickly absorb information about the interlocking systems such as timing behaviour and routes and analyse the impact on railway capacity.

The subschema is currently under development with participation of some European infrastructure managers and the signal manufacturing industry based on railML 3 and UIC's RailTopoModel. A list of use cases for railML's interlocking scheme can be found here IL:UseCases.

Common (CO)

→Main Article: Common

The Common class shall cover all topics, which affect all other railML-schemas alike.

The actual planned tasks and enhancements can be found at Trac-Tickets of the railML development space.
