Railway Standard
The line is single track (with grading and other provisions for a second track), and has 22 passing loops. The maximum axle weight will be 25 tonnes at 120 km/h (freight trains) and 250 km/h permitted for passenger trains (as with all new lines, the earthworks must have time to adjust to the intended traffic). Curves have a radius of 3200 m or more, except for the passage of Örnsköldsvik (down to 600 m) and a few between 2000 and 2500 m. The maximum grade is one percent.

Famous quotes containing the words railway and/or standard:
“Her personality had an architectonic quality; I think of her when I see some of the great London railway termini, especially St. Pancras, with its soot and turrets, and she overshadowed her own daughters, whom she did not understand—my mother, who liked things to be nice; my dotty aunt. But my mother had not the strength to put even some physical distance between them, let alone keep the old monster at emotional arm’s length.”
—Angela Carter (1940–1992)
“As long as male behavior is taken to be the norm, there can be no serious questioning of male traits and behavior. A norm is by definition a standard for judging; it is not itself subject to judgment.”
—Myriam Miedzian, U.S. author. Boys Will Be Boys, ch. 1 (1991)
