Comparison analysis of indonesian railway track quality index calculation results with european standards (EN) using multibody dynamic system simulation results (Case study: DAOP VIII Lawang - Malang)

Train is one of the most popular modes of land transportation. With the increasing number of train enthusiasts in Indonesia, it must be supported by adequate facilities and quality. Therefore, it takes the value of the Track Quality Index which consists of geometric parameters such as alignment, longitudinal level, cross level, and track gauge. A review of the calculation of the TQI value can be used as a basis for repair and maintenance of railroads. The study was carried out using several methodologies to obtain the geometric quality values of the presented lines and compared them with each other, namely calculations using the railway method in Indonesia (KAI) as well as European standards (EN). Then compared with the simulation, the results show that the KAI TQI standard is less comprehensive, so it needs to be equipped with an assessment based on the maximum deviation of each rail geometry parameter. This research is expected to be an input in the calculation of comprehensive rail quality standards in Indonesia.
