So, as most of us know by now, there was transport 'chaos' this morning. Not least on the tube – according to the TFL Realtime Travel News page 10 out of the 12 lines on the underground network were knackered at 9am today.
Credit to London Underground though. They could have used this morning’s light dusting of snow as a predictably lazy excuse for all of the problems, but they’ve risen above that. Instead they were attributing most of the delays to signal failures at: Hainault, Westminster, Olympia, Whitechapel, Neasden, Golders Green, Uxbridge, Finsbury Park and “somewhere on the East London Line”. Crikey.
So here's a question: can snow cause signal failures? Even at parts of the network that are properly underground (like Westminster)? Or were all of those tube lines just unlucky to suffer near-simultaneous signal failures this morning?
