May 12 (UPI) — A fire at an electrical substation disrupted train service throughout London, including the underground Tube, and forced evacuations at stations on Monday.<\/p>\n
At about 2:30 p.m. local time, key parts of the Underground and Overground networks were hit, with Elizabeth, Bakerloo, Jubilee and Northern lines affected, Sky News reported<\/a>. By Monday night<\/a>, most services of the 20 lines had been restored.\n<\/p>\n London Fire Brigade<\/a> said a cable fault led to an electrical substation fire in west London’s Maida Vale residential neighborhood. The cause is under investigation.<\/p>\n The Jubilee line was suspended on its busiest stretch between London Bridge and Finchley Road, the Independent reported<\/a>.<\/p>\n Heathrow Airport passengers and staff who normally use the Piccadilly line were affected.<\/p>\n At Piccadilly Circus, one passenger said they were stuck on their train for “quite a long time.”\n<\/p>\n “Lots of tourists with huge suitcases, plus elderly and disabled people having to climb all the standstill escalators as no lifts were working,” the person said.<\/p>\n Electrical power is handled by National Grid.<\/p>\n
