Brief introduction to Transnet Freight Rail
Transnet Freight Rail is one of the nine divisions of Transnet SOC, an unsubsidised public entity that has
more than six business divisions namely: Transnet Freight Rail (formerly known as Spoornet) the
largest division of Transnet which owns, maintains and operates the long - distance freight track
lines. Transnet Rail Engineering (Transwerk) for rolling stock manufacture, maintenance &
refurbishment. Transnet National Port Authority the landlord of all eight commercial ports of the
country. Transnet Port Terminal (SAPO) manages all port cargo terminals in all eight ports. Transnet
Pipelines (Petronet) fuel and gas pipeline division which pumps cargo to storage, processing terminals
through high pressurised pipelines over long- distances. Transtel manages the largest communication
lines in Africa. Propnet real estate agent in charge of all Transnet’s properties. Transnet’s passenger
division managed by PRASA is Metrorail provides commuter rail services and shares track lines with
TFR. Freight Dynamics manages all containerised, refrigerated cargo and general cargo, lastly South
African Airways a subsidiary of Transnet since the 90’s (National Treasury Report: Transnet Cross-
subsidies
;2020).
Though some divisions are public owned on behalf of the government, Transnet operates as an
independent financially self-sustaining Commercialised and Corpotarised environment. Currently
some amended policies suggest some of its role as the owner and regulator of the national assets is
rather conflicting and should be restructured or unbundled to pave a way for Public Private Partnerships
to bid for upgrading some inoperable Branch Lines and facilitate competition within the rail sector to
increase rail’s competitiveness & increasing its market
