Denmark : DSB - Arriva
Denmark has a comprehensive and efficient railway network run by DSB/Danske Statsbaner (Danish State Railways) which includes the private rail company, Arriva trains.
Modern InterCity trains connect Copenhagen and Zealand with main towns on an hourly basis. You can also get to Odense on the island Funen in 1¼ hours with half-hourly trains while InterCityLyn trains take just 3 hours from Aarhus to Copenhagen.
Eurail Passes for Denmark are valid on Arriva trains, DSB-First and S-Tog or S-trains, Copenhagen’s city centre (and inner suburbs) rail network operated by Danske Statsbaner. Copenhagen airport’s station directly links to central Copenhagen and Malmö.
Denmark is well-placed for Scandinavian travel. A tunnel/bridge link connects Copenhagen with Malmö (Sweden) and frequent trains go to Elsinore. On the Swedish side of the Öresund strait, trains run to Helsingborg and Kristianstad while high-speed X2000 trains connect Copenhagen to Stockhom in 5 hours 15 minutes. You can book night trains to Cologne/Dortmund, Stuttgart and Munich in Germany.
Most Danske Statsbaner or Arriva trains don’t need reservations, but we recommend them on InterCity/InterCity Lyn trains. You’ll also need to reserve seats on the X2000 between Copenhagen and Stockholm, ICE International trains and night trains like the CityNightLine.
