The Haramain High Speed Rail project also known as the "Western Railway" or "Makkah-Medina high speed railway", is a 453.0 kilometres (281.5 mi) (449.2 kilometres of main line, plus a branch connection to KAIA airport: 3.75) high-speed inter-city rail transport system under construction in Saudi Arabia.
It will link the Muslim holy cities of Medina and Mecca via King Abdullah Economic City, Rabigh, Jeddah, and King Abdulaziz International Airport. It will connect with the national network at Jeddah.
The rail line is planned to provide a safe and comfortable transport in 300 kilometres per hour (190 mph) electric trains. Construction started in March 2009. The railway is expected to carry three million passengers a year, including many Hajj and Umrah pilgrims, helping to relieve traffic congestion on the roads.
