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

Hi Dave,

Do you know where the UK maxspeed figures would have originally come
from? I assume it's some form of open source database rather than
someone foolishly walking the tracks.
There are multiple ways to get railway maxspeed data
(1) data with a compatible license
(2) mapping maxspeed signs along the railway line either by
walking/cycling along the line or by GPS/photo/video mapping by train
(3) GPS logging at a train and assuming the train /always/ drives at the
maximum permitted speed – a bad assumption because sometimes trains
drive slower because they are not delayed, try to save energy or try
have a slower freight or local train ahead of them.
I do not know if there is a public available dataset with UK maxspeeds
which has a compatible license. I suggest you to join OpenRailwayMap IRC
this evening (UTC) and ask if someone knows a dataset like (1).
irc.oftc.net
#OpenRailwayMap
In Germany we are only allowed to use (2) and (3).
