Hello

I want to travel to Canary Warf from Worcester Park using the London
Overground from Clapham Junction.

I will touch in at Worcester Park but do I have to touch the pink reader
at Clapham Junction before I get on the Overground...?

Thanks for your help.




I would.
The single fare finder says "To ensure you are charged the appropriate
fare you must touch on the pink card reader if interchanging at Canada
Water". No mention on CLJ. This selects 2.70/2.10 in place of 5.40/4.20.

I found Single Fare Finder on an Android 'phone with: start at
https://tfl.gov.uk, Menu/Fares & payments/Single fare finder.
