National Rail and London Overground

The London Overground (LO) is a National Rail Line but is not under the National Rail branding. TfL's journey planner has accommodated the new name, as has National Rail's, but National Rail hasn't yet published an ATOC London Connections Map with this and the other changes. They're also going to have to update the Oyster PAYG in National Rail map - a copy of which (it's not a link) is published on TfL's website. I'm sure the mappers at FWT are on the case.
