What do you do when the centre tracks are the fast tracks and the outer 2 tracks are the slow stopping lines, like the line near me that runs from London Bridge to East Croydon via Forrest Hill. This is in contrast to some other stations such as those in North London, where you the 2 fast t

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 line

All Network Rail speed restrictions are in mph, except a handful (very distinctive) ones that are in both mph and kph (the units for the kph speed are on the sign) near the mouth of the Channel Tunnel (essentially the route between there and the freight yards). I don't believe there are any speed
