**** taxis.
You know it's so convenient and less stressful to take train. No sane person would choose a taxi above a train.
I've seen a video someone took driving something like 120km/s on a road next to the railway lines and one of these new blue electric trains eased past him.
These bad boys:

Deas quiet, air-conditioned, and automatic doors which prevents the train from moving if not closed. In-carriage displays of current and next station details (so you don't get lost), the displays are combined with an audio announcement. I was also pleasantly surprised the other day when the driver cut off the announcement to say we'll be 3 minutes late in Bellville as he's moving a little slower so as to not have to wait before Bellville because another train coming from the other direction has to make use of our designated platform due to an issue on their own platform.
We'll always have our African problems, but by God, this is a step in the right direction!
Upgrade the rail infrastructure and dramatically increase the number of lines and stations.
You'll be saving rail travel for both commuters and freight.
Offer 100k to taxi owners to crush their taxis.
