Going Loco: Mexico's Maya Train - Part 2

Qasa Alom continues his journey on the Maya Train, the brand-new line that connects the towns, villages and historic sites of Mexico's Yucatan peninsula. He heads into the interior to see how the region's natural heritage has coped with what's been called 'one of the greatest construction projects in the world', stopping at the spectacular Bat Volcano of Calakmul, seeing some of the oldest living organisms on earth and exploring underneath the rock on which the peninsula is built.
