Comparative Analysis of Track Access Charge (TAC) Calculation Using Full Costing and Pricing Methods for Cement Train in Java

Abstract

Train operators that utilize state-owned railway infrastructure are obliged to pay a Track Access Charge (TAC). In Indonesia, the TAC formula employed is based on the full costing method. However, this TAC calculation formula does not currently accommodate the policies of multiple operators with varying types of train services and infrastructure. An alternative method for calculating TAC, known as the pricing method is available. In this research, TAC calculations were performed using both the full costing and pricing methods for freight trains in the Java region. From the TAC calculations using both methods, a comparison was made to determine the differences in the results, providing insights and references to the government in formulating policies and regulations related to the development of a relevant TAC formula for railway operators. The full costing method's TAC calculation is contingent on priority factors, while the pricing method's TAC calculation depends on axle load, axle count, unsprung mass, and train speed. Components of the pricing method's calculation directly influence the impact on railway infrastructure damage. In conclusion, the pricing method for TAC is considered fairer and more pertinent for all railway operators when making TAC payments to the government.
