DSB, an abbreviation of "Danske Statsbaner" (, "Danish State Railways"), is the largest Danish train operating company, and the largest in Scandinavia. While DSB is responsible for passenger train operation on most of the Danish railways, goods transport and railway maintenance are outside its scope. DSB runs a commuter rail system, called the S-train, in the area around the Danish capital, Copenhagen, that connects the different areas and suburbs in the greater metropolitan area. DSB used to operate some trains in Sweden, but has since August 2017 lost all their contracts.
