The Camden High Line makes a small appearance in the Camley Street Neighbourhood Plan published by Camden Council in July 2019. The eastern entrance to the High Line is on the northern end of Camley Street itself:
The Camden High Line was suggested by blogger Oliver O’Brien in 2015 and is being actively pursued by the Camden Town Unlimited BID. The aim is to create a linear, green and open walkway between King’s Cross and Camden Town. The route would utilise a disused railway line that runs alongside the existing Overground route. O’Brien identified a route whose eastern end terminated at Camley Street, using the existing stairs towards the northern end of Camley Street on the north side of the railway.
A revitalised Camley Street, combined with the High Line, would make for a scenic walking route between Camden Town and King’s Cross Central, or, combined with the canal link, an interesting triangular walk.
The Camley Street Plan also shows it on one of its maps:
