Time Out must be short of material. It's not a new idea, and it doesn't seem to be referencing any new announcement. Still had at least one semaphore signal last time I saw it from the Met line. If it does happen it won't be any time soon.
There was a bit of business in Brent council. I don't think it was anything important in itself - some kind of report back on progress (or lack thereof), but it was enough to trigger some of the media.
Brent of course includes the two important new stations, where new cross-connections would happen: Harleden and Neasden. Mind you, the same radial lines are already connected to the Overground (atbka Mildmay) at Willesden and West Hampstead, so the added journey possibilities are not so great in reality.
