The Gautrain is a new standard gauge electric high-speed rail line linking Johannesburg, Pretoria and the O.R.Tambo international airport. Operations on the East-West line and the airport connection started on 8 June 2010 (in time for the World Cup). On August 2, 2011, the service from Rosebank to Hatfield (Pretoria) commenced and with the opening of the Park Station in Johannesburg on 7 June 2012 the system was completed. There are 24 four-car sets which were all delivered by November 2010.
There are connecting bus services from all train stations. Buses use the prepaid "Goldcard" that is also used by the train. A bus ride connecting to a train (or vice-versa) within 60 minutes costs 6 Rand, otherwise 20 Rand.
The bus fleet consists of Mercedes-Benz O500U and UA (articulated) vehicles with Brazilian Caio Mondego H bodywork, assembled or finished in South Africa by Busmark 2000. The buses are numbered in the 8000/8100-series totalling at least an estimated 125 vehicles, with the newest ones being the articulated buses. The standard vehicles come in two versions: with one door or two doors. The vehicle numbers are suffixed by S (Single door), D (Double door) or A (Articulated).
The company website gives ample information on the system, inlcuding maps and timetables.
