§ The railroad line is 476 km long. Due to the difficult terrain and large investments, it had to be single track, with axle load of 25 t.

§ Depending on the railroad line elements (gradients and radius of curves) the trains run at the speed of 75-100 km/h between the stations. The line goes mainly through mountainous regions with maximum gradient of 25%. The lowest altitude point on the railway is in Bar (3 m) and the highest one in Kolasin (1032 m). One of the features of this railway is that 24% of its total length is in tunnels.

§ There are 254 tunnels with the total length of 114,437 m.

- Zlatibor 6,169 m,
- Goles 4,964 m,
- Trebesica 5,170 m,
- Sozina 6,171 m.

§ Defying water flows, valleys and canyons, 206 concrete bridges were built in the length of 10,760 m and 28 steel bridges of the total length 3,833 m.

§ The bridges longer than 300 m are:
- Lim III 395 m,
- Ljubovija 311 m,
- Tara II 340 m,
- Mala Rijeka 499 m.
