A Woolwich dwelling, Canary Wharf working mate texted me this morning
saying "tipped up at 8:30. found Trams were going only as far as
Blackwall - nothing as far as Poplar for at least the next 4 trains.
getting on the bus to N Greenwich".

Possibly because the official opening was at 9.00 this morning, with
Boris and the press in attendance, so I doubt there was a normal service
pattern around then.
