It used to straddle the border but it appears that Elverson Road is now in that spot?
As far as I can see from my Oyster history there has been no change to charging for my journeys to and from Lewisham of late, so is this a change that is going to be implemented in the future, or is the new map just misleading?
It’s definitely a mapping error and Lewisham is still dual zoned 2/3. One thing that gives that away is that the station name is still boxed which is the rule for stations which straddle zones, even in the sausage around Stratford where everything is both 2 and 3.
I’ve drawn it to the attention of my contact at TfL though, so thank you for sharing.
