Route map

The Dammam–Riyadh Line is a passenger railway line in Saudi Arabia, linking the Eastern Province's capital city of Dammam with the Saudi capital Riyadh. The 449 km line has 4 stations. It is operated by the Saudi Railways Organization (SRO). The total journey time is about 4.5 hours.

Construction

The Dammam–Riyadh Line was opened in 1981.

Upgrade

There is an upgrade ongoing, where bridges replace level crossings[1] and a bypass of the centre city of Hofuf.[2] This shall allow 200 km/h speed.

In 2014, the SRO awarded a contract worth US $1.6 million to a consortium led by Spanish firm Consultrans to study alignments for a high-speed line linking Riyadh and Dammam.[3]

Stations

Riyadh station.

The stations at Dammam, Hufuf and Riyadh were designed by Lucio Barbera and designed and built between 1978 and 1980. They were opened for public service in 1981. The terminus stations in Dammam and Riyadh are extremely similar and consist of a rectangular hall of three naves separated by two lines of pillars along the ends of the tracks and two wings at the ends of the main hall along the outer tracks. The design is based on the layout of some mosques along the Mediterranean Sea, where the prayer hall is located at one side of a court with lesser wings along the sides of the court.[4] The style and decoration of the buildings uses elements such as triangular openings to construct windows and arcades and parapets with rectangular steps,[5] elements bearing a resemblance to Nejd architecture but also common in other Arab architecture. The station building in Hufuf lies to the east of the through line along one side. The decoration is very similar to the stations in Dammam and Riyadh.

There are four stations on the Dammam-Riyadh line:

Signaling system

In 2007, the SRO contracted a consortium made up of Siemens Transportation Systems and the Saudi Arabian Nour Communications Company to modernize both the Dammam–Riyadh Line and the cargo line of SRO rail network. The line will be equipped with signalling technology including an electronic interlocking as core of the installation and Trainguard 100 for ETCS Level 1. GSM-Railway (GSM-R) mobile radio technology will be used for communications on the entire rail network.[15]
