Sounds like a normal day commuting on SWT to me. There were "speed restrictions at Waterloo" this morning as well, but I was less than ten minutes late.

Gosh, this entirely passed me by. I had so much trouble getting to sleep last night (really bad headache which is only subsiding now) that I decided to get up a little later, have a proper breakfast and catch the 8:56 from Wokingham to Bracknell instead of my usual train (7:56). It turned up, I got on, no problem.

Which only goes to prove that all this 'getting up early and going to work' stuff is a sad mistake.
