What means that ?
1) Does mean it more consecutive days of fastrack ( 7 consecutive days of the late night shutdown on a section of a line instead of 5 or even 15 - 30 consecutive days ) ? Does mean fastrack on more lines in the same moment ?
2) I think that no line will be totally closed, but only segments of a line ? Is it right ?
