South African steam railways - Natal.
A pair of South African Railways 15F-class 4-8-2 locomotives head a coal train on the Newcastle - Utrecht branch (northern Natal) in 1975. This erstwhile lightly-laid route had been upgraded to allow for heavier axle loading, following increased output from Umgala Colliery.
