1970s-2000s

Works began in 1974 by building the bridge across the river Sava and the tunnels "Vračar" and "Dedinje".^[3] The bridge, New Railway Bridge, was finished in 1979,^[4] while the tunnels were finished in 1993 and 1988, respectively.^[2]

The Zemun railway station was built from 1977 to 1981 when was opened, even though it was never fully finished.^[5] In the early 1980s, the marshaling yard in Makiš was arranged. In 1982 the double-track railway Zemun-Zemun Polje was finished and part of the passenger-technical Zemun railway station was built. In 1984 double-track railway New Belgrade-Belgrade Centre, across the New Railway Bridge was finished, so as the "Senjak" tunnel, the continuation of the bridge, which connects it with the Prokop station. In 1988 the two single-track railway tubes ("Dedinje" tunnel) were finished, establishing the connection Belgrade Centre-Rakovica-Jajinci. The tunnel is 3 km (1.9 mi). There were significant problems during the digging under the Humska Street (Partizan Stadium) and the royal palace of Beli Dvor.^[2][6]

Double-track railway Belgrade Centre-Pančevo Bridge, with tunnels "Vračar" and "Stadion", was finished in 1993. The "Vračar" tunnel is 3.5 km (2.2 mi) long. From the Pančevo Bridge an additional double-track tunnel, "Karaburma", 600 m (2,000 ft) long, was also built but it was never in use. That same year, the double-track connecting switch railway "Karađorđev Park" and switch "Dedinje", with railway stations Karađorđev Park and Pančevo Bridge, were also completed. On 7 July 1995, the underground station Vukov Spomenik was opened. As of 2018, most of the stations lack the station buildings or access roads.^[2][6]

Other larger facilities built include:^[2]

• tunnels: "Bežanijska Kosa", "Karaburma", "Kneževac", "Kijevo 1", "Kijevo 2" and "Kijevo 3";
• stations: Tošin Bunar railway station;
• bridges and overpasses: Bridge on the circular road in Rakovica, overpass across the Novi Sad highway and three-forked overpass across the highway at Maleško Brdo-Autokomanda;

In the complex on the part of passenger and goods transport system, by 2018 the following was built in total:

• 15 single-track tunnels (19,744 m (64,777 ft)), three tunnels for two tracks (4,431 m (14,537 ft)), and one multi-track tunnel 200 m (660 ft) long;
• 36 reinforced concrete prestressed railway bridges of the total length 4,960 m (16,270 ft) and road area of 65,255 m² (702,400 sq ft) and seven carriageway brides 957 m (3,140 ft) long and road area of 9,840 m² (105,900 sq ft);
• 12 steel single-track bridges of the total length 1,266 m (4,154 ft) and six bridges for two tracks of total length 2,034 m (6,673 ft).^[7]

Estimated funds for the completion of the junction are 250 million US$, which should be provided from foreign investment and loans. Final date of completion was set for 2010, but nothing has been done by that deadline.

2010s

Gradual moving of trains from the Main station to the new, Prokop station began in the early 2016. In December 2017, all but two national trains were dislocated to "Belgrade Center".^[8] Problems arose immediately. The Prokop is still not finished, has no station building and a proper access road and public transportation connections with the rest of the city. Additionally, it has no facilities for loading and unloading cars from the auto trains nor was ever planned to have one. Still, in January 2018 it was announced that the station will be completely closed for traffic on 1 July 2018, even though none of the projects needed for a complete removal of the railway traffic are finished. The Prokop is incomplete, a projected main freight station in Zemun is not being adapted at all while there is even no project on a Belgrade railway beltway.^[9]

A series of temporary solutions will have to be applied. One is the defunct and deteriorated Topčider station, which will be revitalized and adapted for auto trains. It has one major flaw, a bad public transportation connection (only one tram line, No. 3), so the railway company asked officially for this problem to be solved. It was announced that the official deadline for the construction of the station building in Prokop is 2 years, however there are no funds for it. A second part of the Kuwaiti loan (€50 million) is still not approved and the needed public procurements will be finished by the end of 2018. Freight station in Zemun will be located between the existing stations Zemun and Zemun Polje, on the area of 35 ha (86 acres). Revitalization of the existing 6 km (3.7 mi) of tracks and 14,500 m² (156,000 sq ft) of buildings will be followed by the construction of the 17 km (11 mi) of new tracks and additional 18,800 m² (202,000 sq ft) of edifices. Deadline is also 2 years, but the works will start at the end of 2018. This means that the planned Belgrade railway junction won't be finished before 2021, at best. However, minister for transportation, Zorana Mihajlović, in December 2017 gave conflicting deadlines. She said that the station building in Prokop will be built from April 2018 to April 2019 and that freight station Zemun should be finished by the end of 2018.^[9] In October 2018 a deadline for finishing the Zemun station was extended to early 2022.^[5]

The question of the beltway remains. There is still no project for it, and it is needed especially for the hazardous materials which are now transported right through the city. It was announced that after the Main station is closed, these trains will use the much wider bypass route, Pančevo-Orlovat-Novi Sad railway, which is itself under reconstruction in January 2018. As a permanent solution, a track Beli Potok-Vinča-Pančevo will be built, but the project includes the road beltway along the same route and a road-railway bridge across the Danube. It is not known when it will be built, as the projected cost is €0.5 billion.^[9] In July 2018 the traffic around Kalemegdan was discontinued. As the beltway around the city is not set as a priority, city architect Milutin Folić in July 2018 stated that freight trains will use the routes of BG Voz and go through the tunnels below the central urban areas of the city. They will use it during the nights, when BG Voz is not operational.^[10]

In 2015, prime minister Aleksandar Vučić announced that the high-speed rail Belgrade-Budapest will be operational by 2018.^[11] In 2016 a contract was signed in Riga, Latvia, with Chinese companies China Communications Construction Company and China Railways International for the modernization of the Belgrade-Stara Pazova section. The section is 34.5 km (21.4 mi) long and the works include leveling of all crossings, uniformization of platforms, renovation of all station along the route, underground passages, formation of the green areas, etc. Station which will be reconstructed or adapted include New Belgrade, Tošin Bunar (which will be relocated a bit), Zemun, Zemun Polje, Batajnica, Nova Pazova and Stara Pazova, while stops at Altina and Kamendin will be added. The reconstruction has three phases: Prokop-Zemun, Zemun-Batajnica and Batajnica-Stara Pazova. Phase I and III will be done first. The freight and passenger tracks will be separated in the Batajnica-Stara Pazova section. Works started in November 2017 and the entire project should be finished in 36 months, by November 2020. When everything is said and done, the train speed in the Belgrade-Batajnica section will be 120 km/h (75 mph) and in Batajnica-Stara Pazova section up to 200 km/h (120 mph).^[12] In October 2019 the deadline was moved to fall of 2021.^[11]

On 1 February 2019 the traffic in the northern direction, towards Novi Sad, Subotica, Vienna and Budapest, was completely shut off. The modernization of the tracks was given as a reason, including the construction of the viaduct and tunnel Čortanovci (began on 11 August 2017, deadline 52 months), renovation of the Stara Pazova-Novi Sad section (16 March 2018, deadline 48 months) and the already mentioned Prokop-Stara Pazova section. Renovation of the bypass track for the freight transport to Novi Sad, almost twice longer that the regular one (102.5 km (63.7 mi), via Pančevo, Orlovat and Titel), was completed by January 2019. Also closed are the international lines to Hungary and Austria. Minister Mihajlović said that this is "partially force majeure", and that alternative bus transportation is organized. The traffic will be discontinued at least until 2022, or more than three years.^[13][14]

Complete shut down in February has been described as the "heart attack of the European artery in Serbia". As the passenger transportation was disrupted, the freight one was redirected right through the middle of the Belgrade junction, through the "Vračar" tunnel below downtown. City officials claimed that flammable and explosive materials are not allowed to be transported under the city, but they removed tracks which circled around the urban tissue, along the rivers, because of the Belgrade Waterfront, thus disrupting the transportation. Toxic and other hazardous material was then rerouted into the city tunnels. Railway company stated that this transport is organized only at night simply because of the "psychological reasons", not to irritate the commuters. Also, the experts warned that the Pančevo Bridge is not in good shape enough to take all the additional freight traffic. The CIP Institute originally drafted a plan which would make the Belgrade-Novi Sad railway operational during the entire period of high speed rail construction, but the state government buckled under the pressure from the Chinese investors and Russian contractors and closed it completely. Deputy mayor Goran Vesić stated that hazardous materials "were transported previously through the tunnels and it will continue in the future", saying that whoever says differently is lying. Railway company however, stated that this is not true and that hazardous materials were never transported under the city, but added that the transportation is safe, even though the safety study haven't been finished. There are 6 to 10 trains with hazardous materials passing daily.^[15][16] It was also pointed put that the Vračar tunnel wasn't even projected for the freight traffic.^[17]

Up-to-date expenditures in the Belgrade Junction exceed US$700 million. The major portion of the funds was spent for the freight facilities and the electrification scheme, while a portion was spent for the construction of the passenger facilities.

2020s

Projected in 2008, and in 2015 announced for 2016, construction of the massive intermodal freight terminal ("dry port") in Batajnica began on 13 November 2020.^[35][36] The joint Serbian-Russian scientific and technological council was formed to develop and advance Belgrade's railway system and the tracks grid. The joint project was titled "Belgrade's diagrams" and the first session was held in May 2021.^[37]

The Topčider station was closed again on 1 October 2021 and all lines were rerouted to Prokop, leaving the city without a facility to load cars as the Zemun freight station still wasn't finished.^[38] The loading facility became operational on 17 June 2022.^[39][40] The traffic to Novi Sad, via the new, high-speed rail, was restored on 19 March 2022 - five and a half years since the construction began, three years since the traffic was completely shut down and year and a half after the original deadline. Ceremony was attended by the president of Serbia, Aleksandar Vučić, and prime minister of Hungary, Viktor Orbán.^[41][42]

Transportation minister Tomislav Momirović confirmed in March 2022 that the New Belgrade railway station "will remain" the busiest one, not only in Belgrade but in the entire Serbia,^[41] and majority of passengers on the opening of the high-speed rail used this station. The Prokop remained hampered with numerous problems, and by this time it became apparent that, though it may become an important station in the future, it will never take the role of the former Main railway station. Further solidifying the position of the New Belgrade station as the future central hub, is the decision to build the new Belgrade's central bus station (which used to be back to back to the Main railway station), next to the New Belgrade railway station.^[39] By July 2023, there were 140 trains passing through the New Belgrade railway station on workdays.^[43]

In August 2023, president Vučić announced construction of the 18 km (11 mi) long railway from Prokop to the Belgrade Nikola Tesla Airport by 2026. "Not longer than 15-25 minutes", the route will go via the Zemun, Altina, Zemun Polje and Singidunum stations. After the 2027 EXPO and construction of the new national stadium in the area, the railway will be extended to the stadium and then further to Jakovo, Surčin and Obrenovac.^[44]
