Whilst I appreciate threads have a habit of drifting, how is this
seriously now related to uk.transport.london ?

The same principle may apply to several railway stations on the edge of
London.

For example I happen to know the Herts boundary is very close to
Chorleywood station. So there's a wider issue here about hailability of
hackneys in the vicinity of railway stations very close to licencing
boundaries.
