The Cape mainline is a critical part of South Africa’s rail network, and the completion of reconstruction restores both diesel and electric traction following more than two months of disruption caused by severe weather.
The recovery also illustrates the infrastructure challenge facing TRIM as extreme weather places additional pressure on railway formations, track structures and overhead equipment. Reinstating the route required reconstruction at multiple locations rather than a simple track repair, including washed-away formations, supporting infrastructure and damaged overhead equipment.
Transnet Rail Infrastructure Manager (TRIM) has completed the recovery and reconstruction of the Cape mainline following storm damage and washaways in the Western Cape in May 2026.
Heavy rainfall, strong winds and flooding on 11 and 12 May damaged railway infrastructure at five locations in the Worcester area and caused two washaways at Leeu-Gamka in the Karoo. Sections of the line were closed for more than two months.
TRIM mobilised internal teams and external parties to restore the railway. The work involved rebuilding washed-away track formations and supporting infrastructure, reinstating track structures and overhead track equipment, and replacing mast poles damaged in the storms.
The line reopened to diesel-hauled trains on 31 July 2026. It reopened to electric traction in August 2026, once the reinstated overhead track equipment had been completed and commissioned. TRIM has not given a date for the second reopening.
“The reopening of the Cape Mainline reinforces TRIM’s commitment to maintaining a safe, reliable and resilient rail network and responding decisively to infrastructure disruptions caused by extreme weather,” said TRIM Chief Executive Moshe Motlohi.
