Hmmmmmm which month shall we choose to work on the track in South
London and cause disruption to the Gatwick Express and people trying to
get from London to Gatwick to fly away on summer holidays/ come back
from summer holidays and bring tourists to London and home again. I
know! Just as school holidays start and most of August.

Which forms the largest passenger market; travellers to/from Gatwick
Airport, or commuters (mainly to/from London, but other places too)?

Glad to see the idiots that destroyed Railtrack are doing same great
job at Network Rail.

Or perhaps they are trying to minimise the impact on the people who
spend the most money - those with expensive season tickets.
