Should Woolwich be moved to Zone 3?
Calls have been made to Boris Johnson to move Woolwich Arsenal station to Zone 3 on the London transport map.
It follows the London Mayor's decision to rezone stations in Stratford to help boost regeneration.
An online petition has been set up asking for Woolwich's zone to be shifted in order to reduce the costs for south-east London commuters heading west.
Adam Clark, who started the petition, wrote: "As the opening of Crossrail gets closer and closer, and as the regeneration of Woolwich gains momentum, we think it's important to help the area further benefit from all these positive changes. The number of commuters is growing and this trend is only going to continue."
As well as Stratford's rezoning setting a precedent he also says Woolwich is being looked on unfavourably compared to its neighbours.
"Gallions Reach, just north of the river and further east than Woolwich, is already in Zone 3," he said.
Currently a seven-day travelcard from Zones 1 to 4 costs £45, while a Zone 1 to 3 travelcard is priced at £36.80.
The petition has been signed by nearly 500 people in just two days.
