New hybrid trains to transform Zagreb–Split rail connection being built

Croatia is preparing to introduce a new generation of hybrid trains designed to significantly improve rail travel between Zagreb and Split.

Six electro-diesel trains are currently being built at the production facilities of KONČAR – Electric Vehicles in Zagreb as part of a €57.3 million project financed through a loan from the European Investment Bank (EIB).

The project marks another major step in the modernisation of Croatia’s passenger rail fleet and aims to improve connectivity between the country’s capital and its largest coastal city.

First train arriving in summer 2026

During a visit to the production facilities on 16 March, Croatia’s Deputy Prime Minister and Minister of the Sea, Transport and Infrastructure Oleg Butković said the first train is expected to be delivered in July 2026.

Following the delivery of the first unit, one additional train will be delivered each month, with all six scheduled to be in operation by the end of the year, Croatian Railways Passenger Transport said.

“At the moment, 19 trains for HŽ Passenger Transport are in production, six of which will operate on the Zagreb–Split route,” Butković said.

He added that Croatia has already received 70 new trains in recent years and plans to procure an additional 36 units once financing is secured, continuing the country’s ongoing rail modernisation programme.

Croatian industry behind the project

The development and production of the new hybrid trains involve a large number of engineers from the KONČAR Group working alongside dozens of Croatian companies.

According to KONČAR President Gordan Kolak, the project highlights the strength of domestic industry and innovation.

“Behind every train stands Croatian engineering, domestic development and a wide ecosystem of suppliers,” Kolak said.

He noted that the new electro-diesel model represents the fifth type of train drive system developed by KONČAR, following electric, diesel, electro-battery and battery-powered trains.

Kolak added that the trains incorporate modern technology, full accessibility and high energy efficiency, contributing to Croatia’s green transition and economic growth.

Improved services between Zagreb and Split

The new trains will allow more frequent services between Zagreb and Split and are expected to attract significantly more passengers.

Currently, around 250,000 passengers travel annually on the route.

With more frequent services and modern trains, Croatian Railways Passenger Transport hopes to double that number.

Under the planned timetable changes, three daily departures will run from Zagreb to Split and three in the opposite direction.

The long-term goal is to reach half a million passengers annually on the route.

In addition to the six trains for the Zagreb–Split line, five more hybrid trains have been ordered and are expected to be delivered in 2027. These will serve routes connecting Osijek, Rijeka and Pula via Slovenia.

Designed for Croatia’s mixed rail infrastructure

The railway between Zagreb and Split stretches 429 kilometres, but only the first 103 kilometres between Zagreb and Oštarije are electrified.

The remaining 326 kilometres to Split run on non-electrified track.

The new hybrid trains are designed specifically for this type of infrastructure, allowing them to operate using electric power on electrified sections and diesel propulsion where overhead power lines are not available.

The trains will reach speeds of up to 160 km/h and can be coupled together to increase passenger capacity when needed.

The electro-diesel trains will feature low-floor carriages designed for easy boarding and accessibility.

Each train will include four doors on each side, ramps for wheelchair access, dedicated spaces for bicycles and accessible toilets.

Passengers will also benefit from modern onboard amenities including:

• Free Wi-Fi
• Passenger information systems with visual and audio announcements
• Power outlets
• Video screens for passenger information and content
• Self-service vending machines for food and drinks
• Full video surveillance throughout the passenger area

Each train will offer 150 seats, including 18 seats in first class and 132 in second class.

Officials say the project will not only improve passenger comfort but also enhance the energy efficiency of Croatia’s transport system.

The introduction of the hybrid trains is expected to reduce noise levels and greenhouse gas emissions while strengthening rail as a competitive alternative to road transport.
