This paper analyzes changes in train ticket prices in railway transport by examining fare policies in three European countries France, Italy, and, Germany and, comparing them with the fare system currently implemented in Serbia. Using data collected over a 30-day period, the study focuses on intercity railway lines and observes price variations based on the time of ticket purchase, time of day, and differences between weekdays and weekends. The results show that European operators successfully apply dynamic pricing as a tool for more efficient demand management, resulting in increased revenue and train occupancy. In contrast, in Serbia, prices remain unchanged regardless of circumstances. Dynamic pricing models enable real-time fare adjustment and offer greater flexibility for both operators and passengers. Through comparative analysis, key differences in pricing strategies are identified, as well as opportunities that Serbia could leverage to modernize its pricing system. Based on the findings, the paper proposes pilot projects for dynamic pricing on the newly constructed high-speed railway line, supported by digital tools and demand analytics, to enable a gradual introduction of a modern pricing system aligned with market requirements.
