Gredelj

What Gredelj does

TŽV Gredelj is a Croatian railway vehicle manufacturer founded in 1894 in Zagreb, operating as a wholly-owned subsidiary of Slovak parent Tatravagonka a.s. since December 2021. The company manufactures, reconstructs, modernizes, and maintains diesel and electric locomotives, diesel and electric multiple units, passenger coaches, freight wagons, and trams. Core technical capabilities include in-house design and development (~100 engineers and technicians), CNC machining (Trumpf TruLaser 3030 laser cutting, plasma, punching, bending, turning, milling), certified welding at DIN EN 15085-2 CL-1 (highest level for rolling stock), painting and surface treatment lines, wheel set and bogie workshops, and the proprietary GLC800 locomotive computer control system. Products are designed to UIC and AAR standards and adapted for narrow, standard, and wide rail gauges.

The company generates revenue through project-based B2B contracts covering new manufacturing, modernization, refurbishment, and ongoing maintenance services. Go-to-market is executed via direct enterprise sales, competitive international bidding, and presence at major industry trade fairs (InnoTrans, Transport and Logistic, Trako). Customer base spans national and regional railway operators (Croatian Railways HŽ, Željeznice FBIH), Italian operators (FSE, FER, FS Cargo Trenitalia, FNM), freight logistics firms (Innofreight, Budamar Group), urban transit authorities (ZET), and OEM partners (Siemens Mobility, Končar-Elektrolokomotive via the CROTRAM consortium). Geographic footprint extends across Croatia, Italy, Bosnia and Herzegovina, Germany, Argentina, Guinea, and Saudi Arabia. Pricing is handled through direct quotation and contract negotiation rather than published rates.

As of February 2026, parent Tatravagonka announced the permanent shutdown of all Gredelj production activities by June 2026, with approximately 300 workers to be made redundant. The company had recently secured flagship engagements including the Siemens Mobility night train wagon contract (April 2023) and the Innofreight €2 billion ten-year memorandum (March 2022), but these have not offset a structural decline, and the entity is operating in a wind-down posture.
