A puffing steam train climbs into the Himalaya, a rolling rumble echoes over the holy waters of the Ganges, an astonishing five million commuters rush daily through the Bombay Victoria Terminus - join National Geographic as we journey on one of the world's largest railways. Since 1853, India's railway has been a unifying force. Not only did it physically link distant regions, it also connected the myriad of castes, languages, and religions that comprise India. It's a rich history, riding the sumptuous Palace on Wheels through Rajasthan or the "toy train" to Darjiing, but sadly, the age of steam is dying. At the Black Beauty contest, the beloved steam engines are admired for the last time. From the driver in the steaming locomotive to the station master in the sleepy village, from the family traveling to a wedding to the commuters in the large cities, this great institution reflects the country itself. Many are the faces, and varied are the stories, on THE GREAT INDIAN RAILWAY. - Written by Jeanne Rawlings (Writer)

Stalk the Arctic ice with the fiercest predator, the polar bear, as it prowls one of the most forbidding places on the planet: a hidden kingdom of magnificent creatures. Armed with a keen sense of smell and backed up by 1,700 pounds, fur and fangs, the polar bear stands alone at the top of the food chain. Yet many other hunters manage to survive in and around harsh Arctic waters from the savvy arctic fox to the massive, whiskered walrus. And when the spring comes to the Artic, there is an extraordinary explosion of life - rarely seen anywhere else on earth. Returning to the fridged waters come some of the world's most unusual beasts, the ghostly white Bulaga Whale, the endangered bowhead whale, the Narwal with its 23-foot tusk. And hidden beneath the violent, shifting ice lies a secret world of strange creatures that patrol dark sea floors on the carcasses of the dead... and each other. The Arctic ice is revealed as a place of danger and drama as animals are stranded on frozen waters, trapped between moving sheets of ice, and caught in the struggle to survive. Brave the worst that nature has to offer.
