Many years ago my dad worked for SATS (South African Transport Services) at Cape Town harbour. At the time SATS was owned by the government. On 1 April in 1990 a strange thing (IMHO) happened: SATS was restructured and became Transnet Limited, an incorporated company with the State as its sole shareholder.
At the time it was said that SATS was being "privatised", but this made no sense to me since the State owned all the shares. If you happen to know the rationale behind this action, please do let us know.
Okay, so where I was headed with that story was simply that this diesel goods train belongs to Transnet Freight Rail, a division of Transnet Limited, and formerly (last year) known as Spoornet (which translated means rail network).
