On NR lines where LU trains run, their rules
state that it's the normal line speed, unless there's a lower speed
for station limits.
Why should lines within station limits be lower than in the section?

They need to be (exceptionally not generally) at a number of stations
due to deviation of the route from a straight line (e.g. Willesden and
Harrow on the DC line).
