Unlike in other provinces, here in Western Cape, 60% of transport users travel by train.— Riana Scott, Metrorail
All the lines converge at Cape Town station she says, where there is a great deal of industry and many employees travel to the city daily. The trains operate across six municipal areas and 75% of residential areas.
So when the trains are not working it hits Cape Town hard.
And that's what happened on Saturday, says Scott.
Vandals struck in three very strategic areas. They targeted signal cabins, and the result of that was basically the analogy I can use is as if you are at OR Tambo and suddenly they have no radar control - they can't plot a single flight or allow people to land or take off.— Riana Scott, Metrorail
Scott says it was too dangerous to run trains without being able to see what was going on.
Metrorail is fixing the problem. Each signal cabin has 500 cables which need to be individually reconnected and the operation is time consuming.
She explains why arranging buses is impractical in already congested Cape Town.
