So, the Night Tube 'dummy run' weekend: how did that go then?
The diplomatic way to put it would be that at least there were no passengers and management have a week to put it right. Their to-do list includes dealing with: signs that point passengers to the closed parts of stations; digital announcers on Central line trains telling people to change to lines that aren't running (and which can't be turned off); staff being desperately shuffled between stations to keep them open; trains in a proper dirty state; plungers taking ages to reset; and engineering works going on where punters are supposed to be walking.
It seems like it's not even Fit for Next Weekend let alone the Future.
Once the passengers arrive, we can perhaps expect some of them, emboldened by booze and inspired by the Olympics, to try hurdling over the 'turtle gates' that are supposed to prevent access to closed parts of the station. Gates that are only shoulder height are hardly an insurmountable obstacle, after all.
