UAE's Etihad Rail is planning to construct a 1,200km rail network at a cost of $11bn from UAE to Saudi Arabia as part of a GCC railway framework under three phases.

UAE's rail network forms part of the GCC Railway Network - linking the UAE to Saudi Arabia via Ghweifat in the west and Oman via Al Ain in the east.

Phase I of the UAE rail network has been awarded to an Italian-UAE joint venture comprising Italy's Saipem, Tecnimont and UAE-based Dodsal Engineering and Construction for AED3.3bn ($900m).
It spans 266km connecting the cities of Habshan and Ruwais in Abu Dhabi's by 2013 and Shah and Habshan by 2014 while the third phase will connect the northern parts of UAE.
The stage-one contract includes civil and track works including the earth works and track's site grading, bridge structures and communication systems.
It also involves design, procurement and construction of the rail line including building a depot at Mirfa.
