Slow Train Through Africa - Season 1 Episode 5

Griff crosses a thousand miles of South Africa, reaching the most southerly passenger railway station on the continent. Griff begins in Pretoria, catching Africa's most modern train on a short journey south, to Johannesburg. On board he almost finds himself in trouble with the security guards for attempting to eat his breakfast, which is against the strict train rules, which also include no singing. Johannesburg is home to over four million people across a vast, sprawling city that grew because of the amounts of gold found underground. The goldmines needed workers and railways were built to transport them.
