Boxholm Ironworks is the first in Sweden to have an electric railway track in 1890. Five years later, the first electric railway opens for passenger traffic. It covers an 11 kilometre stretch between Stockholm and Djursholm.
SJ electrifies the Kiruna–Riksgränsen stretch, which opens in 1915. Then things really take off: the Stockholm–Gothenburg stretch is electrified in 1925, the Stockholm–Malmö stretch in 1934, and the Trelleborg–Riksgränsen stretch in 1942.
Today, 84 percent of the Swedish Transport Administration’s tracks are electrified (about 12,000 km).
