M.A. / The proposal to build the Gautrain rapid-rail link between Pretoria, Johannesburg and Johannesburg International Airport was approved in June 2000 by the Gauteng Provincial Government. It was noted that this particular development could have serious environmental implications for the area involved. The aim of this research is therefore to identify the most suitable terrain in order to optimise the rail route alignment with minimal environmental impact. This will be accomplished by undertaking a terrain suitability analysis. The different high-speed railway types are discussed and their impact on the environment is considered, culminating in an evaluation of the background and status of the proposed Gautrain rapid-rail link. The different approaches to terrain evaluation are discussed in order to draw conclusions relative to the methodology used in this research. Subsequently the activity approach as described by Mitchell (1991) and Hugo et al (1997) was chosen as the methodology to use for this research and the terrain within the study area was classified according to its suitability for the development of the Gautrain rapid-rail link. A Geographic Information System (GIS) was utilised to aid in the terrain suitability analysis. As a result of the analysis an optimised route is proposed and compared to the rail routes already proposed for the Gautrain rapid-rail link. It is imperative that a terrain suitability analysis should form part of the preliminary phase of any environmental management cycle as portrayed in Fuggle & Rabie (1998), in order to identify suitable terrain for the development in question; the rapid-rail link route should be no exception.
