Track Integration Quality Index

Due to the running of high-speed trains and heavy haul trains, the track equipment is damaged more frequently, leading to a threat of running safety. Therefore, how to evaluate the quality, and improve the maintenance of track equipment is scientifically becoming an urgent issue to ensure the transport safety, reliability, and rational allocation of resources. We analyzed the shortage of track by inspection; locomotive cabs also had portable monitor meter detection installed and static checking in data processing and utilization. In the full analysis of their mutually complementary relationship we proposed the track equipment integrated quality evaluation indicator (Track Integration Quality Index) obtained by giving the three indicators, quantified three data, different weights through different grades, and characteristics track testing, then made some recommendations of its calculation method and application. Considering all the data reflecting track quality, Track Integration Quality Index is able to overcome the TQI's one-sidedness and provides an indicator of equipment quality assessment for secondary lines.
