The line beyond Redmire closed completely in April 1964, but aggregate traffic from the quarry there kept the rest of the line open. Leyburn also retained its status as a goods depot until 1982 (and a passing loop and signal box), but latterly the entire route operated as a 'one train' single line. The limestone traffic to and from Teesside ended in December 1992 but after a spell of disuse, traffic resumed in the form of Ministry of Defence military equipment trains to Redmire (where they were transferred for onward movement to/from Catterick Garrison).
