Should the Northumberland line railway expand to include Morpeth, Cramlington or even Edinburgh?

The Northumberland Line reopened in 2024 with stations including Bedlington and plans for more local services in the county. Morpeth and Cramlington already have East Coast Main Line stops with direct trains to Edinburgh. Recent discussions focus on whether to route more local trains to these stations for better connectivity or invest in cross-border services north to Scotland.
