Railway journeys: old school romanticism at its finest. Here are some of the world’s most scenic railway journeys to consider traveling on for your next vacation.

South Africa has its fair share of luxury, multi-day train travel options but that’s not to say that equally staggering views can’t be had from a no-frills train.

Tickets on this Metrorail journey are dirt cheap, bypassing all of the intricacies of the Cape Town’s city tracks and gliding you straight to the coast, with the glorious blue of the ocean by your side all the way to your destination.
