The Impact of Double-Track Construction towards Utilization: A Case Study of Surabaya – Madiun Segment

Determining railway service quality is crucial due to its potential impact on train schedules, leading to delays. Service quality is evaluated through its utilization, which is equivalent to the infrastructure's ability to handle the current traffic volume. By understanding utilization levels, it is anticipated that operational quality can be effectively implemented. This is because utilization serves as an indicator of the relationship between traffic flow and available capacity. Furthermore, railway capacity is analyzed using the UIC code 405 method. The construction of a double-track on the Surabaya-Madiun segment is progressing, with 50% of the project operational by the end of 2019. A simplified simulation phase is conducted under the reference condition of 50% double-track operation, and the results are analyzed to determine railway capacity. The analysis findings in this study reveal that the construction of a double-track on the Surabaya-Madiun segment has resulted in a 27% increase in utilization.
