Beginnings in the 1878
After a British proposal the 1878 Berlin Congress permitted Austria-Hungary to occupy and govern Bosnia-Herzegovina instead of Turkey. Railways were built primarily as strategic military facilities and they were connecting southern Adriatic ports with cities in the hinterland and with Central Europe.
1879
The 190 km long Brod–Zenica military railway was built to support maneuvers and supply troops. It was completed in 1879, using the 760 mm.
1880
Dubrovnik requests to connect Gruž (Dalmatian and Zelenika railway) with the railway track Sarajevo-Metković (Narenta railway).
1882
The Zenica–Sarajevo extension opened in 1882, with a loading gauge the same as that used on 1,000 mm (3 ft 3 3⁄8 in) gauge railways, which was thought to be sufficient for general traffic including passenger services. The Brod–Zenica–Sarajevo (Bosna railway) Bosna Bahn provided the basis for the narrow-gauge railway network which was later established in Bosnia-Herzegovina.
1885
Southern Line, and the first section of that railway from Metković-Mostar (Narenta railway), in the length of 42.4 km, was opened for traffic on 13 June, 1885.
