(LONDON) -- A maintenance mishap Thursday left one of London's busiest train stations stuck, literally, when a wave of fast-drying cement flooded into a signal control room. At first, transportation officials said run-of-the-mill flooding was to blame for the delays on the Victoria line, however, pictures of the true nature of the mucky mess soon escaped online and went viral.
According to Metro.Uk, contractors poured a container of the cement into an escalator near the electronics-filled room, but the gray wave burst into the adjoining room and got all over the control room's wiring and other computer equipment.
The matter appears to have been resolved, with the Victoria line tweeting Friday morning, "Tweet tweet! Morning morning! Huge apologies for Victorial line yesterday, it's now running with a good service. Stay in touch for updates."
