The Waterloo & City line crosses under the Thames and runs between Waterloo and Bank stations with no intermediate stops. Its primary traffic is bringing commuters from south-western England arriving into Waterloo mainline station to the City of London.
It was opened by the Waterloo & City Railway Company in 1898. It was the second electric tube railway to open in London after Northern line.
It is the shortest line of the London Underground (2.4km) and takes 4 minutes to travel from end to end. In absolute terms, it is the least used line.
- The Waterloo & City line has the fewest scheduled for peak period service at just five.
- Not connected to any other rail route; rolling stock is removed for refurbishment using a crane on the road above the depot
