Presumably TfL waited 3 weeks to share this good news in order to cautiously stack up some evidence that LU really deserved to win, to preempt us grumbly, naysaying local users who are routinely stumped by delays, closures, engineering works, faulty escalators, overcrowding (overheating to be looked forward to) and the fact that we can't even sweeten the pill with a spot of home time tippling on the tube any more. So the announcement is laced with additional news of record passenger numbers (necessity of use not a great indicator of quality) and the completely uncontextualised statement that "passenger satisfaction ratings also hit a new high with average scores reaching 79 out of 100." .
As Annie Mole points out, it does look a little suspect that the judges of The Metros are entirely UK based with the event held in London, when its purpose is to celebrate the global mass transit industry. Hmm, hang on - last year's winner was Copenhagen Metro and the awards were held in... Copenhagen. Ah.
London's rivals for the gong were Paris, Madrid, Berlin and aforementioned 08 winner, Copenhagen. Those familiar with these cities' metros please share their inadequacies so we can properly revel in this frankly incredible, in the truest sense, achievement.
