I use it most weekdays to go from London Bridge to Canary Wharf. Greatest way to travel in for a stress free start to the day. The new timetable is excellent and suits me better - they seem to have more people using it now it's every 15 minutes.
It was very spooky in the fog, mind you........
Good value really if you get a pass c\rd as they don't expire like a season tikcet.
