A.P. Moller – Maersk would like to inform you about expected railway capacity reduction at the Port of Koper. There are several extensive investment works underway in the area of Slovenian public railway infrastructure that will further intensify in the coming months and impact key rail corridors in Slovenia between June and December 2025.

These infrastructure works are expected to cause significant disruption to rail operations within Slovenia, especially on the Ljubljana–Sežana/Koper line, which serves as the primary rail route to the Port of Koper.

In next years the following investments will have the greatest impact on capacity throughput.

Expected closures till the end of  2025:

Construction works on the Ljubljana-Sežana/Koper line:

• continuous closure of the line on the Divača Gornje Ležeče section from 29.06.2025 to 30.07.2025,
• continuous closure of one line on the Verd-Logatec section from 04.08.2025 to 10.12.2025.

Reconstruction works at Jesenice station from September 2025 to May 2027:

• in September 2025, the reconstruction of Jesenica station begins with a weekend closure,
• from March 2026 to January 2027, rail transport technology to and from Austria (in the direction to and from Slovenia) will be restricted.

Reconstruction works at Ljubljana station from 06.10.2025 to January 2026:

• during this period, only two lines for freight and passenger rail transport will be passable through Ljubljana station.

All of mentioned caused a 50 % reduction in capacity, reduced frequency, complicated planning and delays.
