Improvements in the performance of computers and peripheral equipment which process inspection results data and convert it into indexes required for control and work have also been remarkable. No matter how great the amount of track data, it can now be processed at a marginal cost.
Furthermore, research into track dynamics has progressed, and recently, the scope of data application has expanded through methods that incorporate information theory concepts such as the transmission function, response function and filters in the relationship between tracks and running cars. However, ideal track control methods cannot be established immediately, and at this stage, all possible areas are being introduced in sequence as subsystems. Equipment will have to be developed, systems constructed, efforts put into staff training and other activities undertaken, keeping in mind a vision for the future.
3.6 Track Maintenance Work
Track maintenance works take many forms according to the railway development stage and socio-economic factors. When the transport volume of railways rises and speed becomes higher, deterioration, accordingly, maintenance work, increases. At the same time, the interval between trains in which to perform maintenance is shortened. Generally harsh conditions also tend to cause difficulties in securing the labor required for track maintenance work.
Before these situations arise, action must be taken by strengthening the tracks to reduce the amount of maintenance, and by revising the work system, mechanizing the work and other activities.
(1) Revision of the Work System
By the revision of the work system, we mean separating of inspections and maintenance work, and changing from day-time to night-time work, from as-required to periodic repairs, from individual to group work, and from directly managed to outside contracted work.
Japan has undergone all these revisions. However, it is important that systems are to be revised to match the conditions of railway lines by first testing the new systems in some sections to discover their merits and demerits.
(2) Mechanization
The mechanization of maintenance work is essential to modem society. Young people would rather use a hand-held tamper than a beater, and would prefer to operating a multiple tie-tamper rather than using a hand-held tamper. Mechanization must be encouraged to draw young workers to track maintenance work.
