Mgitywa said they will prioritise Covid-19 hygiene protocols inside trains and on platforms, and also reminded passengers to wear masks regularly.
"No eating or drinking will be allowed inside trains to ensure passengers keep their masks on at all times," said Mgitywa.
Prasa has encouraged passengers, who don't feel well, to not board trains.
Passengers are encouraged to observe social distance markers inside the train, social distance markings next to the ticket office and at the platforms at all times.
