Mecca Metro whisks pilgrims between holy sites

 Muslims beginning the annual Hajj pilgrimage in Saudi Arabia have a new way to avoid the crowds: an elevated light-rail that will whisk them between Holy sites.

The first phase of the train project, called the Mecca Metro, will transport pilgrims between Mina, Arafat and Muzdalifa. The three stops on the pilgrims' journey trace the steps of the Prophet Muhammed and Abraham.

The annual Islamic pilgrimage draws some 2.5 million worshippers each year. The sheer numbers present authorities with a challenge in preventing stampedes at holy sites, fires in pilgrim encampments and the spread of disease.

Officials hope the 11-mile (18-kilometer) train, which begins operating on Sunday, will alleviate crowding.
