A word of caution from a group (none-rail) of which I am a member
"As a few people are starting to vanish on Christmas breaks ..." I'm posting this message about the dangers of going away at Christmas. OK - so that's not quite what the poster intended to imply, I'm sure!
Spotting a little other humour around ... I'm not sure if anyone else has flagged this up:

To any of our regular users going away over Christmas, have a great time. And remember that if you get bored, the Internet is just about everywhere these day and although the trains won't be running, this forum will still be. I may take the opportunity to do a little engineering work, which may interfere a little with services - so please do allow extra time for your posts ...
