Japanese National Railways has computerized the planning of the maintenance of its 26,000 km of main lines, 13,000 km of sidings, and 70,000 switches. JNR has programmed the replacement of 2,000 km of rail yearly. For each individual turnout, data is stored on the parts involved, on the results of annual inspections, and on the speed and volume of movements. Initially tie condition has involved the almost 38 million wood ties on JNR but the growing number of prestressed concrete ties are to be included in the future. Seven high-speed track inspection cars are being fitted to provide input for a maintenance planning system. While problems remain, computerization of maintenance equipment control, track improvement planning and track work estimates are being made.
