A limited number of trains have resumed in Cape Town on Wednesday morning.
Metrorail began the trial operations which will end on Friday.
The trains will only run on the southern line, between Cape Town and Retreat.
The service is operating between 05h00 and 09h00, and again between 15h00 and 19h00.
The trains have been suspended since the start of lockdown later in March.
Commuters who are not wearing masks, won’t be allowed to use trains.
Physical distance markers are in place, from the platforms to inside the train carriages.
No eating or drinking on the trains will be allowed, and informal traders are prohibited.
Metrorail says security guards and marshals will be visible to help enforcement these strict new measures.
