Investigation of the Geometrical Deterioration Process of Tramway Superstructure Systems – A Case Study

Abstract

Tramway tracks deteriorate over time due to operational loads, environmental conditions, and structural factors. This study analyzes the geometric degradation of Budapest's tramway tracks using long-term measurements. Track gauge and longitudinal level were assessed with the TrackScan 4.01 instrument to evaluate deterioration across different superstructure types. Findings indicate that concrete slab tracks experience gauge widening, while embedded rail systems tend to narrow under similar conditions, with structural design playing a greater role than traffic intensity. Measurement limitations highlight the need for improved monitoring tools. These insights support more effective maintenance strategies, ensuring greater durability and sustainability.
