Interestingly, during the recent closure between Shadwell and Highbury, I heard a digital announcement at an underground station that said "The East London line is closed." Yet officially, it hasn't been referred to as that since 2007!
Severe Delays are occurring to my thought patterns due to overworking and long hours!
That's far better than "London Overground is partially suspended" without any further information being given. Most recently heard at Bank when I was actually intending to use the Overground later in my journey - although as it was a problem on one of the lines out of Liverpool Street and I was heading for the DC line from Euston it wasn't actually at all relevant.
