Scenic Lines:
*South Devon Coast, between Starcross and Teignmouth
*Exmouth branch south of Topsham, skirting the River Exe estuary
*Gunnislake branch...great scenary, if the line was a bit of a stagger!
*The Cambrian Coast route to Pwllheli, especially between Dovey Junction and Aberdovey, skirting round the Dovey Estury, then hugging the cliffs around Friog, the crossing of Barmouth bridge etc
*The Arun Valley Line between Horsham and Ford.
*Swanley-Otford via Eynsford
*Rather surprising, the Dover Priory-Faversham route via Canterbury East has its scenic moments, such as between Faversham and Canterbury, and Dover and ShepherdsWell.
*Edinburgh-Aberdeen route for most of its length, along the Firth of Forth, then through the rolling Fife countryside, before rejoining the coast for much of the route to Aberdeen.
*The Highland mainline, particularly Drumachder pass!
