Hampstead Heath became a fully accessible station the other week, with the introduction of two new lifts to both platforms bringing step-free access to this Overground station.
The ticket hall area has been redesigned as well with a wide gate, newer regular ticket gates and a step free entrance.
We of course went down there to have a look (photos tomorrow) but immediately you can have a sneak preview of the 3D map of what it looks like which will be in the next update of the App.
