Commuters faced travel chaos in the run-up to the bank holiday, after Bank and Monument stations were closed and several lines were disrupted after a fire alert.
Although the stations have now reopened, several lines, including the Waterloo and City line, were still disrupted.
Transport for London cannot give an estimate of when normal service will resume at this time:

There are also reports of light flooding caused by the fire:
So....Bank Station is closed because of flooding (not sure how deep) caused by the fire alert earlier. #sprinkler— BBC London Travel (@BBCTravelAlert) August 28, 2015
There are also severe delay on the Circle and Hammersmith and City lines, with parts of the lines suspended, due to emergency engineering work at Ladbroke Grove.
