The Overground's Secret Station

The London Overground has a secret station ... which doesnt appear on the normal Tube Map, and only has three trains a day that use it. It was time to spend a day catching all three services, and tick off the Overground's secret station .... Battersea Park.

You can only do it on a Monday to Friday, or Sunday.
