Abstract
Dominating SZD track design and maintenance strategy is the need to minimize interruptions to traffic flow. Heat treatment is used to prolong rail life, and large end-loading tracklaying cranes permit rapid removal and replacement of complete panels while the adjacent track still carries traffic. On double-track lines machines may be concentrated so that several 2-km segments of track are replaced during a staggered sequence of six-hour occupations which takes advantage of one prearranged gap in the passage of trains.
