I reside in Johannesburg and would just like to know from the people that stay in Pretoria and work in Johannesburg what they think of the gautrain in terms of efficiency. Have they used the gautrain and if they have, what do they think of it?

Better to ask in the Gautrain thread: http://www.skyscrapercity.com/showthread.php?p=83343447#post83343447

yes please post questions there. you are more than welcome to create threads here for the pretoria stations etc... but all discussion should take place in the one thread.
