On the note of 'Ferryhill could be like Chester-le-Street', I know that, from Eureka's May introduction, Chester-le-Street will cease to be an 'InterCity' station, as XC Reading-Newcastle stops will be replaced by TPE calling hourly on their Manchester Airport-Newcastle runs.
I think we've discussed this to death at times, but my favourites (for likely (re)opening) would be Parkway stations in the middle of nowhere, like the one proposed at Worcester to replace Shrub Hill (whose passenger figures have plummeted over recent years) with a vast Parkway station on the site of land where the Cotswold Line (between Worcester and Evesham) and XC Line (between Cheltenham and Bromsgrove) cross each other. Kenilworth, Ilkeston (in the heart of Toton's vast yard) and a station in the Edinburgh Airport region of Scotland (south of South Gyle, north of Haymarket IIRC), called something like Gongar look the most probable new stations within the foreseeable future.
I have seen tonnes of documents from NR's website about this topic, just can't remember where...
Probable schemes (at least before the spending cuts etc):
Alloa-Dunfermline, Pye Corner station (on the new Newport-Ebbw Vale Line curve), and not too much more...
