Congratulations to engineers working during holidays

The public are complaining about the near-total shutdown of Britain's railways over the holiday period. It is an inconvenience, but allows Network Rail to carry out major projects in one go which would otherwise take months and cost a lot more. It takes a lot of time to bring equipment to the site and clear up afterwards, so this makes sense. People would complain even more if the system was allowed to fall to pieces.

Congratulations to the people who have given up their holiday period to do this essential work.
