 After this date, the remaining R class locomotives on the register were used for special enthusiast workings.R 706, R 769 and R 749 continued in this role until boiler and mechanical conditions made them too costly to maintain and they too were withdrawn, leaving only R 707 and R 761 in operable condition.Scrappings had commenced with R 755 in 1960, which had been involved in a serious rear-end collision with a freight train earlier that year, and continued through the decade.
