Railway line Podsused Tvornica – Samobor – Bregana is designed as a railway line for suburban passenger transport. The construction was conceived in two phases. The first phase consists of the construction of the railway from Podsused Tvornica station to the Perivoj station, and the second phase from the Perivoj station to the Bregana station. The construction of the railway line Podsused Tvornica - Samobor - Perivoj will be of great importance for many passengers from the town of Samobor and Sveta Nedelja, but also the surrounding settlements of Bregana, Domaslovac, Strmec, Orešje and Bestovje who travel daily to Zagreb. The use of rail transport will reduce traffic congestion on the roads, ensure the improvement of the demographic picture of the cities of Samobor, Sveta Nedelja, but also its surroundings, contribute to economic and tourist development and better connections with the city of Zagreb. Workers, pupils and students currently travel to Zagreb by buses and cars, which in addition to the existing traffic jams that prolong travel time and parking issues, also increases environmental pollution and thus further burdens the city center. One of the basic strategic goals of the development of railway infrastructure and railway passenger traffic in central Croatia is the expansion of the ring around the city of Zagreb, which will become an integral part of the suburban railway transport system of the city of Zagreb. Changes in the lifestyle and habits of the population, as well as comfort and flexibility of private cars on the one hand and underdeveloped public transport on the other, often lead to a traffic collapse in larger cities. This also happened in Zagreb, especially in its western part, where due to congestion of roads, there is a slowdown in traffic and delays in peak daily loads. Public transport between Zagreb and Samobor and Sveta Nedelja is based exclusively on bus traffic. Although it transports about 50% of passengers on that route, it isn`t efficient enough compared to private cars, and it has become unreliable and unsafe, which deters people from using it.
