The PRASA DUAL is a bi-mode locomotive specifically designed for passenger services in South Africa and which loosely relates to Stadler's EURO DUAL. Ordered in a quantity of 50 locomotives through Swifambo Rail Leasing in 2013, the PRASA DUAL introduced a new cab design that moves away from the design used for the EURO series up till then. Note the difference with the AFRO 4000 design. The PRASA DUAL has 1,067 mm bogies and has a maximum speed of 140 km/h. In electric mode, the loco has a power output of 3 MW. In diesel mode, the Caterpillar C175-16 engine can deliver up to 2.8 MW.
Due to a dispute between PRASA and Swifambo Rail Leasing and internal disputes within PRASA, the status of the PRASA DUAL and AFRO 4000 orders is unclear. At the moment of writing (May 2017), the orders seemed to be on hold awaiting an outcome. A number of locos had already been constructed, but were kept at the works in Albuixech.
