South Africa put the finishing touches to its World Cup preparations, rolling out the continent's first high-speed rail link on Tuesday and announcing plans to bus fans from stadium to stadium. The three-billion-dollar Gautrain began whisking passengers from Johannesburg's international airport into the uptown Sandton district, just three days before the tournament begins. The 160-kilometre-an-hour (100 mph) link will be one of the key legacies of the tournament and is intended to show that Africa can build transport facilities to rival those of anywhere in the world. "I have been in Johannesburg just for one hour -- the airport and here -- but I really thought this was a first world service," Costa Rican football journalist Gustavo Jimenez told a foreign news agency as he stepped off the train at Sandton.
