Dellner Couplers AB is a Swedish original equipment manufacturer of train connection systems as couplers, gangway systems and dampers. The headquarter of the company is located in Vika in the Falun Municipality. Dellner is owned by the investment organisation EQT AB and has 19 subsidiaries worldwide with around 1,100 employees. In 2018, the company generated annual sales of around SEK 1.9 billion (EUR 180 million).[3]

History

Dellner was founded in 1941 by the Swedish engineer Jan Dellner.[4] The first customer was Swedish State Railways, for whom the Engineering Bureau Dellner produced automatic couplers. In the following years, the company, based in the small town of Vika in central Sweden, expanded its business and supplied automatic couplers to numerous customers in Europe, such as the Paris Metro, SNCF, Rome Metro and Italian State Railways.[5]

In 1960, Dellner changed its corporate strategy and focused solely on the Scandinavian and North American markets. In the following years, the company expanded into automatic couplers under the name AB Dellner Malmco in Scandinavia. At the same time, a subsidiary was established in North America. At the beginning of the 1980s, the company had around 90 employees working at its Swedish headquarters in Vika and in subsidiaries in the USA and Canada.

Global supplier of fully automatic rail couplers

A turning point in Dellner's corporate history came in 1983, when the company realigned its business strategy to supply train manufacturers and railway operators around the world with automatic train couplers. This decision marked the beginning of Dellner's gradual expansion as a global supplier of train coupling systems.

In recent years, the company has responded to the changing requirements of the rail industry. All over the world, more and more passenger trains have been developed and put on the rails, traveling at ever higher speeds. This technological trend has made the safety factor in train couplings increasingly important. Dellner responded to this new development in the railroad industry by considering the coupling of a train as a safety-relevant component of the entire train system. The former supplier of train couplings became a manufacturer of integrated coupling systems that have been equipped with numerous safety features over the years:

  • In 1985, Dellner was the first manufacturer to launch a coupling with an integrated gas-hydraulic dampers.
  • In 1993, Dellner improved the safety technology of automatic couplers by introducing a deformation tube that sits behind the pivot anchor. It improved energy absorption and helped engineers to create more space for the anti-climb protection and side buffers when designing the couplers.
  • Since 2013, Dellner has been offering coupling systems as part of an integrated crash energy management system: With the use of software developed in-house, coupling systems can now be configured for each train type to provide optimum protection in the event of collisions and other train accidents.

Dellner's coupling business in Sweden has traded under various names over the years. In 1952, the Engineering Bureau Dellner was renamed Runnvika Mechanical Workshop. Later, the coupling business traded under the legal names Jan Dellner & Co, AB Dellner Malmco and finally as Dellner Couplers AB. In 1992, Dellner Invest AB was founded as an umbrella company for Dellner Couplers.[6]

After the collapse of the Soviet Union and the economic opening of Eastern Europe, Dellner expanded into the countries of the former Warsaw Pact. After 1997, Poland became an important location for Dellner with a branch in Gdynia, where more and more production capacities were relocated in addition to services over subsequent years.

Diversification, growth and restructuring

In 2003, the holding company Dellner Invest acquired a Swedish company called Precima, a specialist in - dampers and buffers for trains and other industrial applications. The Precima business was integrated into a newly founded subsidiary called Dellner Dampers, which formed a new business unit of Dellner Invest.[7]

In 2009, Dellner Invest acquired a British gangway systems manufacturer called Woodville, which formed a new business unit of Dellner Invest called Dellner Woodville.[8]

Until 2019, Dellner Couplers and Dellner Dampers were both part of the holding company Dellner Invest, which also included the companies Dellner Brakes, Dellner Woodville and Pintsch Bubenzer (50 percent).[9]

In June 2019, the Swedish private equity firm EQT acquired Dellner Couplers AB together with its global subsidiaries including Dellner Dampers AB from Dellner Invest.[10] These two companies now operate under the Dellner Couplers brand.

Since then, the remaining companies of the parent holding company Dellner Invest (as well as some newly created companies) have been operating under the roof of the newly founded Dellner Group.[11]

Dellner Couplers and Dellner Group are two entirely separate companies. Whereas Dellner Couplers is focused on providing train connection systems, Dellner Group is focused on delivering breaks, hydraulics, polymers and glass for various industries and the transportation sector.

In early 2021, Dellner acquired the couplers business of CAF MiiRA, a subsidiary of the Spanish train and bus producer Construcciones y Auxiliar de Ferrocarriles.[12]

Corporate structure

Dellner Couplers AB has been based in Vika, Sweden, since the company was founded in 1941. The international management team including CEO Peter Woxblom, CFO Thomas Leander and COO Stephan Weng as well as many global business units such as Sales, HR, Dellner Service, R&D, Finance, Quality or Procurement are located here.[13] Dellner has production and service facilities in India, Poland, Sweden, France, Germany, Italy, China, Australia, Brazil, Argentina, Singapore, the United Kingdom and the USA.[14]

The main subsidiaries of Dellner Couplers are:

Dellner Sp. z o.o.

Since its foundation in 1997, Dellner Poland has developed as the largest production facility for automatic couplers within the Dellner companies. Dellner employs around 370 people locally at its plant in Miszewko near the port city of Gdynia. In addition to the production and final assembly of couplers, Poland also serves as Dellner's distribution center for various Eastern and Southern European countries.[15]

Dellner India Pvt Ltd.

Dellner is represented in India by a total of 170 employees at two locations: a service center for couplers and gangways is located in Noida in the state of Uttar Pradesh, and Dellner has a production facility for gangways and couplers in Mevalurkuppam near the southern Indian port city of Chennai.[16]

Dellner Limited

A further production facility is located in Swadlincote in South Derbyshire, England, where around 165 employees work on the development and production of gangways for the international market. In addition, the site is also responsible for the overhaul of couplers and gangways for the UK market.[17]

Research and Development

Dellner has a long tradition of researching and developing technologies for first couplers and later complete train connection systems. From the very beginning, the company began adapting types of train couplers to the requirements of different passenger trains.[21]

Today, Dellner manufactures all commercially available couplers for passenger trains[22] – from semi-permanent couplers to fully automatic couplers based on the Scharfenberg coupler principle, Tomlinson couplers and SA3 couplers. Dellner has also developed its own type of coupler head, the automatic coupler type 12.[23]

Dellner has also made a name for itself with the modular design of train couplers and the development of a crash energy management system for passenger trains.[24]

Member of the DAC Delivery Program

Dellner has been a member of the Shift2Rail initiative and the European Union's DAC Delivery Program for the development of a digital automatic coupler for freight trains since 2020.[25] The European Union's DAC Delivery Program has set itself the objective of modernising and standardising the couplers used in freight train fleets across the EU to make the coupling of freight trains safer and faster. To this end, all 400,000–450,000 freight wagons in Europe are to be equipped with fully automatic couplers in the coming years.[26]

As part of this program, Dellner has already developed a digital automatic coupler according to the DAC-4 standard as well as a hybrid coupler for locomotives that can be used to smoothly convert old freight train fleets to the new technology.[27] As a member of the European Union's DAC Delivery Program, Dellner is also working on the development of a digital coupler according to the DAC-5 standard.[28]
