Due to the frequent traffic bottlenecks, jams, and the rapid increase in passenger traffic at the nearby Split Airport (doubling between 2013 and 2017 to 3 million passengers, increasing further at a 23% annual rate), the Split Suburban railway is planned to be extended for roughly further, beyond Kaštel Stari to
Split Airport and running to Trogir as an end station. Some older studies from 2000 and 2003 also envisaged extending the line eastward, but this has since been dropped. In 2006, Marijan Klarić, deputy CEO of
HŽ Putnički prijevoz, announced the plans to overhaul the Split suburban railway, electrify the lines, add another set of tracks and extend the line to Trogir, but nothing happened. HŽ Putnički prijevoz invited the town of Split to work together on defining the new Trogir-Airport-Split railway in 2014. In 2017, a conceptual design study for the line was published. It probed into two different paths (north and south from
D8 road), estimating that two viaducts and one tunnel should be built for the line.
Kaštel Kambelovac, Split Airport and
Trogir train stations would also be built from scratch. Split-Trogir line would have an annual capacity of 5.6 million passengers. The calculations estimated the cost at 500 million
kuna.
2017 In August 2017, commemorating the anniversary of the re-establishment of the railway traffic between Split and the continental Croatia after the
war in 1995, Split mayor
Krstulović Opara announced the construction of the railway to
Split Airport as "everyone's dream", vowing "not to stop" until the line is completed. In October 2017, after expressing the importance of this project, Split mayor met with local counterparts in
Kaštela to discuss the development. Kaštela mayor Denis Ivanović stated that this line would be the most profitable
railway line in Croatia.
2018 After a series of traffic jams on the route between Kastela and Split in March 2018, mayor
Krstulović Opara cited them as a further proof that the road traffic is overwhelmed and that a new railway was necessary. Mayor's opposition, Split
social democrats, also supported the new railway. On April 17, 2018, Split's mayor met with mayors of Kaštela, Solin and Trogir, HŽ Putnički prijevoz chair,
HŽ Infrastruktura board member, as well as Split Airport director, Port authority, and the national
Ministry of Maritime Affairs, Transport and Infrastructure representatives to discuss the project. The railway was deemed especially important in order to link the Split Airport to the
Port of Split (next to the current Split main station) due to many of the 3 million airport passengers travelling to the Dalmatian islands. The integration and
intermodality of the public transport of the Split region with a population of 300,000 was another important goal. Split-Kopilica was mentioned as an intermodal
transport hub in order to alleviate the burden on the current Central Train Station in
Split harbor, something advocated as early as 1939. HŽ Putnički prijevoz strongly supported the project, while the Ministry of Transport would finance the
feasibility study. Kaštela and Trogir mayors stated that the
general urban plan changes with respect to the new rail line have been ongoing in their jurisdictions. Split Airport and Port of Split directors expressed their intention to co-finance the project. train station Under the auspices of the
Croatian Chamber of Commerce and its vice president Mirjana Čagalj, on April 30, 2018, a memorandum establishing the multiyear partnership on Split area rail passenger traffic development was signed between the CR, local authorities, national ministry, and other stakeholders in the project. Two possible routes for the new line to Trogir were mentioned. The first one would branch off from the existing tracks from Kastel Stari to Divulje and further to Trogir. This would mean of new tracks of which would be underground. The section between
Kaštel Stari and
Divulje would cost €70 million, while the section between Divulje and
Trogir would cost between €30 and 80 million. The second route would branch off from
Kaštel Sućurac, requiring of tracks ( underground). The latter would cost €200 million just to reach Divulje. The case and development study planning would take 3–5 years, while the construction of the railway itself another 3–6 years. 8 train compositions would be bought for this line;
Končar representatives presented the
diesel multiple unit HZP 7-023 series to the stakeholders. Rail-workers'
trade union representatives supported investing in the Split suburban rail network as a way to improve HŽ Putnički prijevoz's sustainability, profits, and mission fulfillment. The
Government of Croatia officially supported the project in a cabinet meeting held in Split on May 4, 2018. HŽ Infrastruktura was appointed as a key stakeholder, Ministry of Transport as a coordinator among the stakeholders and the local authorities, while the total cost was estimated at €1.1 billion. However, the Croatian government spoke solely of connecting the
Split Airport with the
Port of Split and building Split-Kopilica as an
intermodal hub. The plans for extending the line to Trogir were dropped. This was reaffirmed on July 17, 2018, by the minister of transport Oleg Butković at the ceremonial opening of Čiovo bridge, stating that connecting Split Airport with the Port of Split by rail is the most important railway project in Croatia. A new study on the proposed Split-Kastela-Airport-Trogir railway was published in the railway engineering journal in June 2018. It probed into the feasibility of two options: either linking the Split airport/Trogir with the existing
M604 railway from
Kaštel Stari ( track) on far west end of the urban area or from
Kaštel Sućurac, very close to Split proper (12.6k. The latter would effectively create a proper suburban rail line connecting the entire Kastela area with Split, airport, and Trogir. The former would cost around 100-150 million euros, while the latter would cost 230-280 million due to the longer track and the route complexity (a tunnel underneath the D-8 road). At a July 19 on-site meeting with the Split area mayors and the state secretary for transport, the CEO of HŽ Putnički prijevoz declared the opening of the new stations on the existing track (Split-H.B.Z., Split-Dujmovača, The path of the new extended track and the point where it will branch off from the existing
Split-Knin-Zagreb railway is yet to be defined. Split mayor emphasized the need to refurbish the railway infrastructure not only for the suburban traffic, but also for the more efficient railway link between Central Europe and Zagreb, and Split and Dalmatia. On September 30,
Split county prefect commented that the renovation and reconstruction of the existing
M604 line section Split-Kastel Stari (Rudine) would commence already in 2019, with the construction of the link between the M604 and Split Airport / Trogir starting in 2021. This would imply the preference for the simpler solution instead of the new line running through/underneath Kastela proper. In November, a Kastela-based NGO came in favour of the new track through Kastela proper due to its commuting nature. In December 2018, public stakeholders and local authorities together with HŽ Putnički prijevoz agreed on relocating the main railway hub and (temporarily) a new central bus station to Kopilica station (officially
Split Predgrade), where a
Park and Ride spot will be built as well. The construction was planned to finish in three months time, by June 2019. The lease for the property was also signed. The intention is to bring the commuting, long-distance bus and tourist traffic to Kopilica and then channel it onto Split urban metro, terminating at the current Main Railway Station in Split harbour. Trains between Kopilica and Split Main Station would run each 10 minutes and the ride would last for 3 minutes. Starting from March 2019, CR will open three new stations (Split-Dujmovača, Sveti Kajo and
Solin-Širine) on the existing line, adding more commuters further out of the city, north from Kopilica. The existing pre-determined spot in railway tunnel between Kopilica and Split Main Station will be equipped and opened as an underground Split-H.B.Z. station. Split authorities will stimulate bus operators to use Kopilica (Split-Predgrade) as their terminal by charging 700-800kn per entry to the inner city center. as well as by the members of the Split City Council. Answering questions regarding
electrification and timing of the construction, Split deputy mayor Nino Vela stated at a Council meeting that electrification was discussed with HŽ Infrastruktura. However, this would require substantial investments and construction of a major
traction substation. The opening and integration of first five stations will be prioritized, with the construction of the Split-H.B.Z. underground station to start in 2020. Split chamber of architects (
Društvo arhitekata Split) publicly criticized and rejected both the design and the temporary nature of Kopilica
intermodal transport hub. The opposition in Split city council pointed at unresolved legal and real estate ownership issues around Kopilica station (Split-Predgrade).
2019 The City of Split published a
tender for the (re)construction of temporary Kopilica hub, planning to spend 5 million HRK, but only one company replied and submitted an offer, estimating the cost at over 14 million HRK. Due to the cost discrepancy, city authorities cancelled the
call for bids and announced a launch of a new one. A new bid was launched on 25 January, reducing the construction work deemed necessary (reducing P+R parking places and canopies), and increasing the expected cost by more than 30%. Split mayor Krstulovic-Opara stated in an interview to
Vecernji list on January 19 that his priority is to connect Trogir, Kastela, Solin and Split agglomeration with rail. - and
Gredelj-produced
HŽ 7023 diesel multiple unit is to serve the line starting from summer 2019 In January 2019, internet news portal
T-portal reported that the
feasibility study (contrary to the earlier studies, such as that of Matić, Nosal and Mikec from 2018) concluded that the connection between
Kaštel Stari station (on the existing
M604 tracks) via Rudine to
Split Airport, bypassing Kastela proper, is the most favourable solution to integrate the airport onto the suburban railway. Its construction is planned to finish by 2025–6. People living in the buildings around Kopilica station expressed their disapproval for the plans. The January issue of
Građevinar, journal of the Croatian Association of Civil Engineers, reported that the planned route to Split Airport will branch off earlier, from
Kaštel Kambelovac station, running along
D58 and thus through Kaštela proper. Civil engineers of Split criticized the way forward regarding Kopilica hub. City representatives announced that one train operating every 10–12 minutes in peak hours will serve the line, while they are negotiating the addition of a second train. Split chamber of architects president criticized the lack of development studies and any traffic impact studies. In mid-February, two companies submitted their bids for the construction tender for temporary Kopilica hub. Together with the construction supervision, costs of refurbishing Kopilica hub were estimated at 11 million HRK, while the reconstruction of adjacent Hercegovacka street, started in February, cost additional 2.2 million. Bid was awarded to Čitić gradnja. Citizens living in 52 households around Kopilica [split-Predgrade] station, heavily concerned about the plans, lack of transparency, and their future life quality around the hub and the bus/train station, organized a protest. The opposition in Split council called for the plans of a temporary hub in Kopilica to be scrapped and a proper architectural and urban planning solution to be devised, estimating the time frame unrealistic. In March it was reported that the rail tunnel does not have the necessary permits, which would result in shelving the plans for the Split-H.B.Z. metro station, but the city administration dismissed those claims. In a town hall meeting, Split city representatives claimed that the frequency of trains running between Kopilica hub and Split Main Station will follow from the needs as defined by the city administration and that HŽ Infrastruktura have already started refurbishing Rudine station. Split chapter of the Croatian Chamber of Commerce presented the plan for connecting Split Airport through Kopilica with the city center to airport management in an on-site March 14 meeting. In mid-March, Split city administration presented the first draft of the
EBRD co-financed
masterplan concerning urban redevelopment, dubbed "Split United." The plan includes
light-rail connecting Split airport to Split harbor via Kopilica hub. An electrified rail line connecting the two is seen as a crucial factor. The funds for
electrification of the existing rail line and the construction of the new segment are planned to be sought in
EU cohesion funds between 2020 and 2027. State secretary in the
Ministry of transport, T. Mihotić, remarked that the goal is to connect
Trogir to the railway as well, while the electrification timeline is not on the table as this line is not on the priority list of HŽ Infrastruktura. Split Main Railway Station, located on the eastern part of Split harbour, was proposed to be retained as a
terminus, dug in underground and refurbished. These plans were heavily criticized by mayor heading the preceding city administration. On March 20, Croatian minister for transport and infrastructure Oleg Butkovic visited Split Airport and stated that the of new tracks necessary to connect the airport to Split with rail are in the planning process by HŽ Infrastruktura and that he hopes that the work will commence in 2021. In early April, HŽ Infrastruktura published an open bid for plans to renovate the railway tunnel and to build an underground station "Split-H.B.Z." inside of it. The plan foresees exclusive use of diesel trains in the tunnel. In September it was reported that, out of three proposed options, Kastela city administration supported the railway line extension from Kastel Kambelovac as opposed to branching off further away, at Kastel Stari station (€300 million), despite the higher cost. However, Kastela mayor wanted to probe into digging the line underground, which was deemed too expensive. Additionally, Kastela mayor also proposed changes to the latter layout option (branching off from Kastela Stari station / Rudine hamlet), citing conservation and agriculture damage as main reasons. In October, deeming Kastela proposal too difficult as it contains high elevation, HŽ Infrastruktura came back to the Ministry of Transport with yet another layout proposal. The new tracks would branch off from Kastel Kambelovac and would be built on pillars between the
D8 road dual carriageway. CR-Infrastructure claimed that this option would be cheaper than digging the rail underground, the construction would cause less interruption, and there would be no
legal or expropriation issues.
2020 In March 2020, HŽ Infrastruktura board member Darko Barišić presented ongoing plans to local stakeholders. They would invest 3,6 million HRK in reconstruction of Split-Predgrade station; further 7,5 million will be spent on building new stations (Dujmovača, Solin-Širina and Sveti Kajo), with construction work to commence in spring 2020. Underground station Split - HBZ was estimated to cost 60 million. Rudine, a new station where the new railway to Split Airport and further to Trogir would branch off from M604, is yet to be planned pending the selection of the optimal route after the feasibility study. Barisic said CR are to electrify the line.
Since 2020 No progress has been made since 2020. The construction of the Split-HBZ station was to be completed in 2021. , the construction works have not begun. In 2021, Ivica Puljak was elected mayor of Split, defeating Vice Mihanović, the candidate of Croatia's ruling HDZ party. During the election campaign, the Split metro was completely out of focus. , it's still out of focus. Neither local nor national politicians talk about it. ==Map==
