The Kingdom of Saudi Arabia (“KSA”) is developing a new railway network to a world-class system which includes the construction of a new passenger railway line from Makkah to Madinah via Jeddah (about 450 km) called the HHR. The HHR will be a high speed electrified passenger line, primarily designed to provide a fast, comfortable, reliable and safe mode of transport for Umrah and Hajj pilgrims and commuters travelling between Makkah and Jeddah
The HHR will be a high speed (max speed of 360 km/h, with commercial speed of 320 km/h) electrified passenger double line between Makkah, Jeddah and Madinah. The length between Jeddah and Makkah is approximately 110 km and 334 km between Jeddah and Madinah. Out of the total of 444 km the length in rural areas is 390 km and 54 km in urban areas. There will be five passenger station.
he main objective of the project ranges the supervision of the installation: signalling systems based on electronic interlocking; mobile telecommunications systems based on GSM-R; fixed telecommunications network based on optical fibre; control and protection automated system of trains (European Train Control System - ERTMS/ETCS – level 1); centre of traffic control; sensors; power supply.
The main goal is improving the security level of the network operations, as well as increasing the traffic capacity of the both lines: Dammam - Hofuf – Riyadh of 449 Km, and Dammam - Hofuf- Harad - Al Kharj – Riyadh of 556 Km.
ETCS and GSM-R systems allow the interoperability of the system, by normalizing the control and protection functions of the trains and making easy the information interchange between equipments.
