[OSM-talk] User WJtW - railway track counts

[Colin Smale]

You forgot Switzerland, where they not only have multiple gauges but
multiple supply systems, including 3-phase.

And what voltage/frequency is common knowledge. At least, I don't
suppose OSM rules dictate that you can only enter that when you have
actually measured the voltage with a multimeter :D
You only need some local knowledge at places where two electrification
systems meet to map where exactly the change is.
Same goes for gauge. Pretty much all mainline railwaytrack in Europe
(except the Iberian peninsula and Russia) is 1435mm and usually people
who know about railways also know where narrowgauge track is used.
