There's a mistake on line 4. I like the XXXXs, shows you've been using it a while.

So the next question is, if I arrive on a Jubilee train at London Bridge should I get out?
How long does it take to get from the tube to the train waiting on the platform? And how long does it take to get to Canada Water and change trains?

I've found myself at London Bridge thinking will I be able to run up the escalator fast enough to get the train or shall I continue to Canada Water, and I've equally found myself thinking will I have enough time to make it to Canada Water for the next train, or should I get out here and take it easy for five minutes?
