The six member states of the Gulf Cooperation Council — the UAE, Saudi Arabia, Bahrain, Kuwait, Oman and Qatar — signed a landmark agreement on Sunday to advance a long-discussed regional railway network, during the 31st Ministerial Committee on Transport and Communications held at Al Riffa Palace in Bahrain.

The agreement lays out a framework for developing and operating a single, integrated and interoperable rail network spanning all six Gulf states, enabling seamless cross-border rail operations between them for the first time. Transport and communications ministers from each member country put their signatures on the document.

Bahrain's Crown Prince and Prime Minister, Prince Salman bin Hamad Al Khalifa, hosted the meeting. GCC Secretary-General Jasem Mohamed Albudaiwi told delegates the deal would "support the development and operation of a single, integrated and interoperable regional railway network," describing it as a milestone after years of technical negotiations among member states.

Discussions at the Bahrain meeting centred on four pillars: project implementation, technical integration of track systems, coordination between national rail authorities, and improving regional connectivity more broadly. According to earlier project updates, the Gulf railway — intended to physically link the six GCC capitals — was roughly halfway complete as of May 2026, with full operations targeted for December 2030.

Regional economists have flagged the project as one of the most ambitious infrastructure undertakings in the Gulf, since it would be the first direct rail corridor connecting passengers and freight across all six member states, potentially cutting road-freight costs significantly between them.

For the UAE, which anchors much of the region's trade and tourism traffic through Dubai and Abu Dhabi, a functioning Gulf rail link would open a new channel for cross-border travel and logistics, giving residents and visitors in Dubai an alternative to road and air travel for regional trips. Transport analysts described Sunday's signing as a concrete step forward after years of discussion around the long-stalled Gulf railway plan.
