Northeast Corridor Track Work.

Major efforts were made in 1979 to improve Northeast Corridor traffic in every way possible, from on-time performance to comfort within the cars and on the rails. Improving service while literally rebuilding the railroad proved a challenge. That year, crews rehabilitated 121 miles of track, including the installation of 296,000 concrete ties and 74 miles of continuous welded rail; installed 173,000 new wood ties; cleaned 55 miles of ballast; surfaced 112 miles of track for high-speed operation; replaced 10,500 ties at interlockings; and renewed 21 turnouts. During extensive work periods, some schedules were lengthened, including those of the popular Metroliner Service (Washington-New York).
