Walking parts of the disused Kelso & Jedburgh Lines

[yorkie]

It looks like it may be possible to walk from Cornhill on Tweet to Nisbet; first along the disused Kelso Line as far as Roxburgh Junction and then along the disused Jedburgh Line as far as Nisbet.

A Wikipedia article includes a map:

Looking at OpenStreetMap, most of the route between Cornhill and Nisbet appears to be walkable (this may not be accurate) with just a few diversions.

• Cornhill on Tweed
• Sunilaws
• Carham
• Sprouston
• Kelso
• Roxburgh Jn
• Nisbet

Has anyone tried to walk this? If so, is it worth doing? Are the sections shown as walkable on OpenStreetMap really walkable?

Kelso to Roxburgh, the only bit I've done, is a well-used path (deviates from the trackbed at the Kelso end - ISTR a cutting has been filled in or is very biggy?).
Google satellite view pretty much confirms Open Street Map throughout.

Geograph appears to confirm that it's walkable too - lots of interesting photos of the trackbed.
