I regularly have to travel out to Canary Wharf, the large office development that has been built over the last quarter of a century in East London on the Isle of Dogs.
Usually I manage to escape before the evening rush hour. Tonight I didn't.
At about 18:10 I got down to the Jubilee Line platforms to head back over to central London. It was horrendous. So far as I could tell, there was nothing wrong with the train service, the problem was that there were simply so many people trying to get on the trains.
After a few minutes I decided that getting on one of those trains was, on that occasion, not for me. I returned to street level and pondered what to do next.
Then I had a brainwave - it was a nice pleasant Summer evening, so what could be better than a trip on the river? It took me a while to find Canary Wharf Pier, but eventually I found myself a Riverboat and had a very pleasant half hour trip up to Embankment, from where I caught the Bakerloo Line up to Marylebone and then a proper train home.
Much nice, most civilised and just £3.55 with a Travelcard.
Door to door the journey took a bit longer than just catching the Jubilee Line, but I could shave some time off the journey because (a) I now know where the pier is and (b) If I were to make the trip regularly I would plan the start of the journey to fit in with the riverboat timetable.
So a new way home, for use in emergencies. Plus we saw Tower bridge in the Up position, something that I don't recall having seen before.
