So, yesterday on the Jubilee Line (and some of us still want to call it the Fleet Line, I'm afraid), at London Bridge the message came over the speakers: "I'm sorry there is a fault on the train, we have to take it out of service. Everybody off, please". OK, not a big problem, those trains are pretty frequent.
But on the platform came "Sorry, there is a fault in the CCTV".
What? Is the CCTV so crucial now? At first we thought it was an anti-terrorism rule, then that there was an insurance (passenger protection) issue.
But no explanation of why the CCTV is so crucial on the Jubilee Line.
Does anyone out there know?
