Capacity requests should be addressed to the Corridor One-Stop Shop, which provides all necessary information about infrastructure capacity along the corridor.

The main goal of the corridor is to facilitate competitive cross-border rail freight between important industrial centres and intermodal terminals in Poland, Slovakia, Hungary and Slovenia, including the Adriatic seaport of Koper, and to provide efficient links to Euro-Asian railway routes in Malaszewice on the Belarus border.

Also known as RFC11, the Amber corridor provides an additional connection towards southeastern Europe via Kelebia on the Hungary - Serbia boarder.

The corridor was established following a joint initiative by Hungary, Poland, Slovakia and Slovenia in February 2017, and was completed within two years following approval by the European Commission.
