Semantic of type and mapping to national usage?

There is a unclear mapping for the classifications of the track in the type attribute. The usage in Germany is currently AFAIK:

• Durchgehendes Hauptgleis; pro Betriebsstelle immer Eines bei je Eingleisiger und Zwei je zweigleisiger Strecken, mit Zugstraße
• Hauptgleis; alle anderen Gleise mit mindestens einer Zugstraße
• Nebengleis; alle anderen Gleise ohne Zugstraßen, nur Rangierfahrten
• Gleisverbindung; Gleise ohne eigenen Verkehrswert, in Weichenverbindungen, Überleitungen

The mapping for mainTrack to Deutschland: durchgehendes Hauptgleis is nearby, but whats with the others:

• secondaryTrack: This is a track not frequently used (e. g. for overtaking only).
• connectingTrack: This is a transfer track from one to another track e. g. in branches, points or cross overs.
• sidingTrack: This is a siding.
• stationTrack: This is a track in a station, possibly with plattforms.
• other:anything: Any value that does not fit any value from the previous enumeration list, fulfilling the constraint: at minimum two characters, whitespace is not allowed. Please, apply Dev:usingAny accordingly.

Any opinions for railML^® 2.x and for a refactoring in railML^® 3.x? --Vasco Paul Kolmorgen (talk) 20:09, 10 April 2017 (CEST)

The track types are defined in Norway according to definition in the train operations regulation (Togremføringsforskriften) https://lovdata.no/dokument/SF/forskrift/2008-02-29-240. The operations regulation divides the line into two types. Either a station or a path (between stations). A station is defined where signals are received or given. The station border is at the home signals. A station has three types of track: main (hovedtogspor), station (togspor) or secondary (øvrige). The distinction is dependent on the route information. The main track is the track to drive into the station in the switches normal position. All other tracks that have (main signal) routes going over them are station tracks (togspor). All other tracks (without main signal routes, like shunting routes or no routes (like shunting areas)) are secondary tracks (øvrige spor). The path has also three types of track: main (hovedspor), siding (sidespor) and connection (not defined in Norway, but sometimes refered to as "forbindelsesspor"). The main track is the main track on the path. To distinguish between the two tracks on a double track line they are referred to in the direction of increasing mileage as right main track (høyre hovedspor) or left main track (venstre hovedspor). This corresponds in railML to dir="up" (right/høyre) and dir="down" (left/venstre). For the ocp operational type other:siding (sidespor) we have the track type siding (sidespor). A siding is in Norway defined as an ocp on the path that is not a station. The ocp has to have an additional track of type siding track. Usual sidings in Norway are factory tracks on the path, for loading and unloading industrial products and timber. The switch leading to the siding track needs to be locked. We do not have connecting tracks in Norway. In case we would have a track connection between the two main tracks on a double tracked line that does not have route og over it, we would call it a connection track (forbindelsesspor). In the case where a single track becomes a double track at an ocp operational type junction or station. Here the main track that goes over the switch in the normal position stays main track all the way through the station. The track in the diverging switch track (not the switches normal position) is the station track (togspor). The two tracks meet at the exit signal. The same happens in the special case where you have no main track that goes unbroken through a station. There the main tracks overlap and end at the exit signal on the other side of the ocp cross section. Then the track continues as type station track.
