Like human arteries, motorways, roads and train-lines are the lifeblood of any healthy megacity. Whether smoothly flowing or clogged, a city's transport routes affect its inhabitants' quality of life. Andrew Marr finds out how the monstrous megacities stay fed. He also finds out just how hard it is to ride a rickshaw taxi in Dhaka, and discovers how the London tube, once the most ground-breaking transport system in the world, has been usurped by modern transport like Shanghai's 400km/hour magnetic railway.
