Wandsworth Town fares

A recent visitor queried why fares from Wandsworth Town to Southeastern destinations did not offer a zone 1 avoiding option via Clapham Junction and Peckham Rye when similar journeys from Putney did have the option.  I’ve queried this with TfL who were already aware of the anomaly and they have confirmed that it should be fixed with the May fares revision.  The issue dated back to 2010 when cash fares from Wandsworth Town did not exist avoiding Waterloo.
