7 July 2005 London bombings
For most of the day, central London's public transport system was largely out of service following the complete closure of the Underground and the Zone 1 bus network. The day after the attacks, most London Underground lines would open again. Most of the Zone 1 bus network would open again too. In August 2005, it was reported that when public transport opened again it lost 30% of passengers that were travelling before, with more people walking to where they want to go instead of using public transport. Most of the Underground, apart from the stations that were damaged by the bombs, opened again the next morning.
