After the Victoria Line has suffered from some concrete related problems with its signalling equipment (it's not cement, that's just an ingredient in concrete) - the fun is nearly over.
Transport for London have said that cleaning of the fast-setting stuff is nearly done, with testing and fixing of equipment to follow.
For now the TfL website says that there is "No service between Warren Street and Brixton while we fix damage caused by Flooding at Victoria. SEVERE DELAYS on the rest of the line."
Great news for those wanting to actually use the underground, not just laugh at it.
