Jeddah: Saudi Arabia's new high-speed railway opened to the public on Thursday, whisking Muslim pilgrims and other travellers between Mecca and Madinah, Islam's holiest cities.
The Haramain High Speed Rail system will transport passengers 450 kilometres (280 miles) via the Red Sea port of Jeddah at speeds of up to 300 kilometres per hour.
Two trains, each carrying 417 passengers, departed from Mecca and Madinah at 8am (0500 GMT), according to Saudi Press Agency.
Two daily services are initially planned in each direction, it said.
Videos posted on social media showed shots of the crew compartment as the first train left Makkah towards Madinah carrying passengers.
Other videos showed passengers disembarking at the Makkah terminal.
Saudi King Salman bin Abdulaziz Al Saud on September 25 inaugurated the high-speed railway, which local officials described as the biggest transportation project in the region.
The new link will slash the travel time between Mecca and Madinah from several hours to 120 minutes, transport officials said.
The rail project was built at a cost of more than $16 billion, according to Saudi media.
In 2011, Saudi Arabia signed a deal for a Spanish consortium to build the rail track, supply 35 high-speed trains and handle a 12-year maintenance contract.
The kingdom is boosting its infrastructure spending and expanding its railways, including with a $22.5 billion metro system under construction in the capital Riyadh, as it seeks to diversify its oil-dependent economy.
The annual Haj pilgrimage, which is to be held in September next year, attracts more than two million Muslims to the Mecca region.
