The notion of getting on a train outside my house and continuing to switch lines until reaching the end of the line in southern South America is one that I find very appealing, given my love of trains. Moreover, Theroux is a traveler after my own heart, keeping his eyes open and his mouth shut and poking around in the places most people aren’t interested in visiting when they’re away from home. It was also interesting to get a small snapshot of various Central and South American countries from the seventies.
