The Passenger Rail Agency of SA (PRASA) has identified contracts worth R1.5bn ($103.4 million) that it says were awarded improperly. The investigation involves 40 companies and took a year to complete. The investigation follows the report of the Public Protector, Thuli Madonsela, that was released in August 2015. Prasa also asked the High Court to review long-term contracts to the value of R7bn ($482.8 million) in five civil actions. This includes a R3.5bn ($241.4 million) contract for 70 locomotives procured from Spanish manufacturer Vossloh Espana.
