Plans are under way to run a freight train from the Syrian port of Lattakia to the Iraqi port of Umm Qasar.
It would mean crossing the entire length of both Syria and Iraq, and would link the Mediterranean with the Persian Gulf (Umm Qasar is close to Basra in southern Iraq).
The two countries have held talks in Lattakia about the difficulties in operating the route. One of those problems is crossing the highly fortified border. Both countries are aiming to have a delay of no more than ten minutes at the border.
The plan is to start running services next month.
