The Dammam–Riyadh line was opened in 1981. Planning for the line started in 1947 with an agreement between King Ibn Saud and ARAMCO to lay a 547 km (340 mi) freight line. Bechtel Construction Company was chosen to build the rail line and a sea port at the eastern end of the line at Dammam, with construction beginning in September 1947. In 1948, veteran American railroad engineer James H. Gildea was hired to oversee the project. The biggest obstacle to building the rail line was the Persian Gulf shallows at Dammam. To allow deep draft vessels to unload, a rail causeway of approximately 7 miles (11.3 km) was built out into the Persian Gulf. The first 5 miles (8.0 km) were a rock causeway and the last couple of miles a section made of a steel trestle. One of the first vessels to unload was a Dutch freighter, in 1950, with a load of rails for construction of the line. The first trains started moving between Dammam and Riyadh in the early 1950s.[1]
Upgrade
[edit]In 2011, it was announced that, as part of a 30-year master plan, there would be upgrades to the line to replace level crossings with grade separations,[2] and to bypass of the centre city of Hofuf.[3] This would allow trains to reach 200 km/h (124 mph).
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.[4]
In December 2015, the SRO President stated that the speed of trains on the line would be raised from 140 to 160 km/h (87 to 99 mph) before the end of the year, and would further be increased to 180 km/h (112 mph) in 2016.[5] On 7 December 2015, SRO began operating passenger services on the line using new CAF push-pull trainsets which operate at 180 km/h (112 mph). The trains entered service as the SRO completed double-tracking of the entire 449 km (279 mi) line.[6]
Derailment
[edit]On 17 February 2017 at about 1:00 am, a train on the line derailed near Dammam, injuring 18 people. The derailment happened after flooding from torrential rains caused the ground under the rail line to erode. The train was carrying 193 passengers and six crew members. SRO stated that all injuries were minor. All passengers were transferred to another train and transported to Dammam station.[7] The line was closed for repair following the accident, and SRO suspended all rail services to Dammam. Services were only operated between Riyadh and Hofuf.[8] Full service was resumed on 23 February 2017.
Stations
[edit]![](http://upload.wikimedia.org/wikipedia/commons/thumb/b/b1/Riyadh_train_station%2C_Saudi_Arabia.jpg/220px-Riyadh_train_station%2C_Saudi_Arabia.jpg)
The stations at Dammam, Hufuf and Riyadh were designed and built by Lucio Barbera 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.[9] The style and decoration of the buildings uses elements such as triangular openings to construct windows, arcades, and parapets with rectangular steps,[10] 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:

1 | Dammam | الدمام | 0 km |
2 | Abqaiq | بقيق | 74 km |

Infrastructure
[edit]Rolling stock
[edit]In 2012, Spanish manufacturer CAF delivered eight fast diesel locomotives, each complete with one trainset comprising one driving van and one trailer passenger car. They also provided four additional passenger cars and two spare locomotives. In 2013 the travel time across the entire line was 4:15, but there is a target of 3:00 for the future.[citation needed]

Tracks
[edit]The line uses type C.W.R UIC 60 rails.[18]
Signaling system
[edit]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 was equipped with signaling technology including an electronic interlocking and Trainguard 100 for ETCS Level 1. GSM-Railway (GSM-R) mobile radio technology was also installed for communication use on the entire rail network.[19]
Operations
[edit]The total journey time is about 4.5 hours.[20] From 1 June 2016, SRO began operating an express train that covered the distance between Riyadh and Dammam in 3 hours 40 minutes. The train departs from Dammam at 9:30AM and from Riyadh at 1:10 PM daily.[20]
