Two trains should be in service (says the website) by 2009, but the TV news report I watched just now said 'by 2007' ! So take your pick.
Interestingly, I got wind from a friend yesterday that there appears to be a new campaign coming up to 'promote' the Vic line as the PR agency were looking for people's suggestions to straplines that could be used. Whether this is for the current system, or whether they're doing all their work 4 years in advance of the new trains being rolled out I'm not sure, but amongst my friends we managed to come up with the following gems:
There's a fine line between E17 and SW9
Your only way to hook up with Seven Sisters
Your fast track to the West End
Two Parks, a Circus and Seven Sisters. What else could you want?
The Queen, Kings Cross, a stones throw from Walthamstow.
Tottenham Hale, Oxford Street sale...
