Monday evening, the District Line was suspended for half an hour, H&C and Circle also suspended, and delays continued well into the evening.
The reason? Loss of train radio from Earl's Court. The reason for that? The Connect project had installed a changeover switch on the desk during the night, but not got round to telling anyone who actually works in the Control Room. Unsurprisingly, the switch was accidentally operated.
No doubt Connect will eventually bring us fabulous new communication capabilities. But its installation has been a litany of chaos (check here, here, here, here for previous hiccups), trampling round the job without regard to those of us who work here. It's another example of why workers would make a much better job of running things than management do.
