[Tagging] Rail maxspeed conversions

[Dave F.]

Thank you for the info

  Another user who's been amending maxspeed to kph has pointed me in the 
direction of ORM's wiki.
http://wiki.openstreetmap.org/wiki/OpenRailwayMap/Tagging#Switches

There are a few inconsistencies with the main maxspeed wiki page: 
Switches & Signals sections & particularly the maxspeed listing in the 
'Tracks' section.

http://wiki.openstreetmap.org/wiki/OpenRailwayMap/Tagging#Tracks

Given your previous reply, do you think the ORM wiki should be amended 
to conform with the main wiki's maxspeed page?

Cheers
Dave F.
