Northumberland Coast Loop – Morpeth North Junction to Benton Junction c.2018)
Starting at Morpeth North Junction (just south of Bothal Viaduct on the East Coast Mainline) the train is taking the direct route as if it was coming from Pegswood, passing through the former station sites at Hepscott and Choppington, then passing through the as then long-disused Bedlington Station, over the Bebside Viaduct, then passing through the sites of soon to open (Summer 2024 and beyond) Blyth Bebside, Newsham, Seaton Delaval and Northumberland Park stations.

Please note that the AWL 57 channel and the individual video are in no way connected or affiliated with this proposal and is shared as a publically available video source to showcase the proposed route only.
