The Stockholm Underground 1975 A Technical Description THE STOCKHOLM UNDERGROUND, 1975 In connection with the opening of the central section--Slussen to Hotorget--of Line 1 of the Stockholm underground railway in 1957, and the inauguration of Line 2 in 1964, technical descriptions of the system were published. With the opening of the major part of the third line, the Jarva Line, yet another important stage in the extension of the underground network will have been completed. Since publication of the second technical description, the second line has also been extended to Botkyrka and to the University. Work is continuing on extensions to Lines 2 and 3. The present technical description has been produced in accordance with a decision reached by the Stockholm County Council Traffic Board, and it deals with the sections added most recently as well as with technically interesting aspects of previous construction work on the Underground. The object is to provide a concise but at the same time comprehensive documentation of the technical methods applied over about thirty years of underground railway construction.
