[Talk-GB] Speed Limit - Trains Was: Re: maxspeed field - what units should we use. etc

[Richard Mann]

It is a different issue. Generally if there are 4 tracks, 2 will be the
fasts and 2 the slows (except on the western when they are mains/reliefs).
Having a pair of lines where virtually nothing stops makes a huge difference
to the service pattern. The actual linespeeds can be quite similar, so
linespeed isn't sufficient to tell them apart.
