Jeroen Wolff is Head of the International Business Development department of Dutch Railways (Nederlandse Spoorwegen, NS). Together with his team of experts, Jeroen is on a strategic and tactical level responsible for qualitative and quantitative expansion of the international rail portfolio, that NS offers in partnerships with other railway companies. Partners include DB Fernverkehr, Thalys, Eurostar, SNCB and OeBB. Jeroen holds a MSc degree in Transport, Infrastructure & Logistics from Delft University of Technology. He joined NS in 2011 as a management trainee after which he moved to Germany and became a project management officer for Abellio Germany’s mobilisation projects in central Germany and North Rhine-Westphalia. Jeroen has intensively worked on re-introducing the (regional) cross-border rail connection between Arnhem and Düsseldorf back in 2017, operated by Abellio under concession from German and Dutch transport authorities. Since November 2019, Jeroen leads the International Business Development Department within NS. Together with its strong partners, NS aims to improve its international rail offer by adding new connections to its portfolio as well as improving attractiveness of international rail over other transport modes. By increasing passenger comfort and reducing journey times, international rail has the unique potential to become the most attractive and environmentally friendly mode of cross-border transport within Europe. Actual examples of improvements that will be put into practice include the introduction of the direct Eurostar connection between Amsterdam/Rotterdam and London (together with partner Eurostar), re-introduction of overnight ‘NightJet’ services to and from Amsterdam (together with partner OeBB) and introduction of new rolling stock on the Amsterdam – Berlin route (together with partner DB). Jeroen is married and has one son. He lives close to Leiden and loves winter sports as well as sailing and spending time with his family. Jeroen is particularly interested in challenges that arise in the complex triangle of engineering, policy and management fields and is energized when theoretical strategies are really put into practice.
