The project will connect all GCC countries and will provide an alternative mode to road, air and sea transportation. It is also expected to significantly contribute to the region's economic growth and diversify of transport modes and reduce costs. The project will also promote and facilitate regional trade and support the national industries of the GCC and neighboring countries, as well as providing employment opportunities for the GCC nationals, and building the required institutional capacity for the development of the railway industry.

The Kingdom of Bahrain will be linked to GCC countries through King Hamad Causeway project which will connect the Kingdom of Bahrain to the Kingdom of Saudi Arabia. This project will be parallel to King Fahd Causeway and includes four road lanes and two rail tracks. The 57-kilometer railway will link the proposed King Hamad International station in Ramli area in the Kingdom of Bahrain with Dammam railway station in Kingdom of Saudi Arabia.

Dammam railway station will be connected to all domestic railways in the Kingdom of Saudi Arabia, while the passenger terminal at King Hamad International Railway Station in Ramli will be connected to the passenger terminal at Bahrain International Airport and other commercial and residential areas in the Kingdom through the proposed Bahrain metro network.

The forecast passengers number using the GCC railway is expected to reach about 8 million passengers per year by 2050. The freight yard in King Hamad International Railway Station will facilitate the transportation of 600,000 containers and 13 million tons of bulk freight
