Bank station was the end point for my Waterloo & City line walk, the first of the 11 lines to be walked as part of the Tube Challenge. At this point it means 2 stations down and 268 to go. This will be the first of 5 total visits to the Bank/Monument complex - the only other station I'll pass through more often will be King's Cross St. Pancras.
Random fact about Bank station - It wasn't until 1940 that the Waterloo and City line platforms were renamed to Bank. Prior to that date the line had terminated at "City" Station, hence the name Waterloo & City line.
