Work has reportedly started on a 111km railway project to connect Kuwait with the rest of the Gulf region.
According to a report by Al Anba newspaper, the first phase of the project will create a new line to Nuwaiseb on the Saudi border and a 153km line linking Kuwait City with Boubyan Port.
Citing senior officials, the newspaper said phase one will cost an estimated $3 billion.
The 2,100km passenger and cargo network stretching through all six Gulf states from Kuwait to Oman has faced technical and bureaucratic obstacles, and stalled as state budgets tightened because of low oil prices.
Bahrain has said it would not connect its network to a neighbouring state, Saudi Arabia, until at least 2023.
