A new Overground station would make sense and be a realistic development, most of east London is now served by the Overground since TfL's investment a few years ago. It's believed that London Overground and played a major role in the gentrification of areas like Shoreditch and Hackney or it at least accelerated its affect.
Walford's fictional location (Bromley by Bow) actually places it a little too far away from any existing London Overground lines but easily within walking distance of a DLR line so maybe it's time for both! West Walford and Walford Central have been mentioned as nearby stations before.
