Dear contributors,
between two platforms, there can be two tracks to serve both platforms, but there can also be more tracks. In the Netherlands, these so called triple station track layouts are mostly found at larger stations (4 or more platform tracks). These third tracks serve two main uses, as described in the attached image. The tracks can be used for through trains (mostly freight), or can be used to divide platforms, or both. Platform divisions are used on Dutch stations that are reaching their capacity. Adding a crossover in the middle of a platform allows two trains using the same platform simultanuously (which doubles the stations capacity for trains up to a certain length). In the example we see a red and green train route using the same platform and a blue train route using a platform on its own (which could be because of the train length). Such track use can of course also happen at the outer platform tracks. The question is how to tag such a third track. In the situation without middle crossover, usage=industrial could apply. But we should keep in mind that these tracks are also used to shunt empty passenger trains (usage=yard). In the situation with middle crossover, usage=main, usage=branch, service=crossover, service=yard and service=siding could be used.
Please share your thoughts. Thank you in advance.
Kind regards, Jeroen
Hi Jeroen & contributors
I know some stations in Germany as well that are using Layout 1.
My opinion: If the middle tracks only serve as a siding - means only few regular trains use it, the outer tracks are preferred if available - I would tag it as service=siding and usage=/as observed/. And vice versa.
Some Examples might help thinking about:
* Solingen main station: - Central track (Nr. 2) is siding, because mainly used for waiting freight trains to be overtaken. - Same for track Nr. 8, which is a train stop with platform, but is only used unregularly, for overtaking, in case of delays etc. http://www.openrailwaymap.org/?lang=de&lat=51.16042799052598&lon=7.0...
* Köln Messe Deutz: - Central tracks largely used by long-distance trains not stopping in this station, NO freight trains. --> I'd prefer usage=main, but have never mapped this. http://www.openrailwaymap.org/?lang=de&lat=50.9407615337433&lon=6.97...
* Siegburg / Bonn: - Only High Speed Service - 2 Central tracks for passenger trains without stop (at least 200 km/h) - 2 Tracks right & left with platforms, only used for stopping there. --> usage=main for central tracks, usage=? for platform tracks http://www.openrailwaymap.org/?lang=de&lat=50.79384089352182&lon=7.2...
Any other opinions are welcome.
regards Christian
