THE OMAN NATIONAL RAILWAY PROJECT
REV A
PAG 6/32
2.1.1. The National Railway Project in the Sultanate of Oman will consist of about 2135 km of railway line, linking - as part of GCC Railway Network – the Oman border with UAE (at Al Ain and Khatmat Milahah) to Muscat, to the central and southern parts of the country at Port of Ad Duqm and Salalah and to the Yemen border. The Oman National Railway is intended to be a double track mixed freight and passenger non-electrified railway line. The planned Oman National Railway (ONR) Network, that will link the most populated areas, the ports and the increasing productive activities of the Sultanate, will be part of the GCC Railway. 2.1.2. The Oman National Rail Project is divided into 9 Segments for a total length of 2135 km, as presented in the following table. Segment

During the first phases of the preliminary design, a Multicriteria analysis has been done to define the best network configuration and Development Plan priorities of the railway system for the Sultanate, reviewing the outcome of all previous Feasibility Studies. The results of this exercise is the current network configuration, approved by the Omani Supreme Council of Planning as shown in the Figure. Phase 1 and Phase 2 include the Segments that are included in the Oman Rail Network Preliminary Design tasks . Phase 3 includes 3 more Segments that would complete the network configuration, planned to be implemented in Phase 3 (Long term developments).

These Segments were designed to operate as a mixed freight and passenger double track railway line, having a maximum permissible axle load of 32.4 tons. The alignment was designed with a design speed of 220 km/h for passenger trains. For heavy freight trains the design speed is 80 km/h, for light freight trains the design speed is 80 km/h. The maximum design speed for turnouts in the junctions is 120 km/h. The planned railway corridor of these segments, along the stretches where it is physically practicable, can permit future speed of 350 km/h for passenger trains. In dual track sections, the minimum distance between the centrelines of the tracks is 4.5 m.

Ibri Station location was identified after having taken into account any instruction given by the main Stakeholders involved, namely:
Ministry of Defense (MOD)
Royal Court Affair (RCA)
Ibri Municipality
Ibri Ministry of Housing
Moreover Ibri Station location, as designed in the revised concept design, lies close to the Ibri logistic Center and near to One Million Palms Project. (Figure 3). The crossed land is definitely flat and no major constraints have to be faced. Minor roads, gas pipelines and small settlements along the roads have to be taken into consideration during the Preliminary Design Phase of Segment 2 B. A viaduct over Wadi Ibri, at around km 10+000 it is likely to be designed.

Both Al Duqm station and Al Duqm railway yard were located in accordance with the last updated version of Al DuqM master plan. The Railway Freight Yard shall be connected with the main gate of the Port of Al Duqm by means of a railway spur.

Map 2 – Segment 3 C North and South solutions
The site survey undertaken along the north route had emphasized some challenging features for the Railway design especially in the final portion of this route, namely:
The vicinity with the Oryx Sanctuary fence (Photo 1)
The difficulty for the accessibility of certain areas due to the lack of any kind of road (Photo 2)
The general complexity of the land compared to the flatness of the south route.
But the most significant reason that led to change from North option to South solution has been the no approval given by both Ministry of environment, Diwan of Royal Court.

THE OMAN NATIONAL RAILWAY PROJECT
REV A
PAG 6/32
2.1.1. The National Railway Project in the Sultanate of Oman will consist of about 2135 km of railway line, linking - as part of GCC Railway Network – the Oman border with UAE (at Al Ain and Khatmat Milahah) to Muscat, to the central and southern parts of the country at Port of Ad Duqm and Salalah and to the Yemen border. The Oman National Railway is intended to be a double track mixed freight and passenger non-electrified railway line. The planned Oman National Railway (ONR) Network, that will link the most populated areas, the ports and the increasing productive activities of the Sultanate, will be part of the GCC Railway. 2.1.2. The Oman National Rail Project is divided into 9 Segments for a total length of 2135 km, as presented in the following table. Segment

During the first phases of the preliminary design, a Multicriteria analysis has been done to define the best network configuration and Development Plan priorities of the railway system for the Sultanate, reviewing the outcome of all previous Feasibility Studies. The results of this exercise is the current network configuration, approved by the Omani Supreme Council of Planning as shown in the Figure. Phase 1 and Phase 2 include the Segments that are included in the Oman Rail Network Preliminary Design tasks . Phase 3 includes 3 more Segments that would complete the network configuration, planned to be implemented in Phase 3 (Long term developments).

These Segments were designed to operate as a mixed freight and passenger double track railway line, having a maximum permissible axle load of 32.4 tons. The alignment was designed with a design speed of 220 km/h for passenger trains. For heavy freight trains the design speed is 80 km/h, for light freight trains the design speed is 80 km/h. The maximum design speed for turnouts in the junctions is 120 km/h. The planned railway corridor of these segments, along the stretches where it is physically practicable, can permit future speed of 350 km/h for passenger trains. In dual track sections, the minimum distance between the centrelines of the tracks is 4.5 m.

Ibri Station location was identified after having taken into account any instruction given by the main Stakeholders involved, namely:
Ministry of Defense (MOD)
Royal Court Affair (RCA)
Ibri Municipality
Ibri Ministry of Housing
Moreover Ibri Station location, as designed in the revised concept design, lies close to the Ibri logistic Center and near to One Million Palms Project. (Figure 3). The crossed land is definitely flat and no major constraints have to be faced. Minor roads, gas pipelines and small settlements along the roads have to be taken into consideration during the Preliminary Design Phase of Segment 2 B. A viaduct over Wadi Ibri, at around km 10+000 it is likely to be designed.

The site survey undertaken along the north route had emphasized some challenging features for the Railway design especially in the final portion of this route, namely:
The vicinity with the Oryx Sanctuary fence (Photo 1)
The difficulty for the accessibility of certain areas due to the lack of any kind of road (Photo 2)
The general complexity of the land compared to the flatness of the south route.
But the most significant reason that led to change from North option to South solution has been the no approval given by both Ministry of environment, Diwan of Royal Court.
