Shoreditch High Street station on the London Overground line* is a Zone 1 station that sits between two Zone 2 stations, Hoxton and Whitechapel. It is the only station on the entire line that sits in Zone 1.

The rest of the stations on the Overground line sit in Zones 2, 3, 4 and 5. This means that people who travel through that one station to their destination have to pay more for going through Zone 1, as Zone 1 fares cost considerably more than fares for other zones. 

I am petitioning for TFL to re-zone Shoreditch High Street station and make it a Zone 2 station, which will save local people, and commuters, who travel through it considerable amounts of money.
