Project characteristics:
The project included the following sub-projects:
1 & 2. Track rehabilitation and overhaul within section Konjic – Čapljina – state border, a total of 100 km. The said railway line was subdivided into two projects: Konjic – Raška Gora and Raška Gora – state border. The section comprises 43 tunnels and 22 bridges and viaducts. The line speed is 80 – 90 km/h. There are 13 stations along the line. The replaced track was composed of S-49 rails fastened to wooden sleepers with “K” type fasteners. The track was installed on limestone ballast bed.
3. Track rehabilitation and overhaul within section Jošavka – Kostajnica, a total length of 64 km. The section comprises 2 tunnels, 27 bridges and 40 level crossings. The replaced track was composed of S-49 rails fastened to wooden sleepers with “K” type fasteners. The track was installed on limestone ballast bed.
4. Reconstruction / rehabilitation of the interlocking system within section Konjic – Čapljina – state border. Interstation dependence was established between three types of stations.
