Evaluation of track geometry maintenance (Tamping) in Swedish heavy haul railroad : a case study

Projekt:

JVTC

Sammanfattning:
Applying the efficient and optimal tamping strategy helps reduce maintenance costs, making operations more cost effective and leading to increased safety and passenger comfort. In this paper, track geometry data from the iron ore line (Malmbanan) in northern Sweden, which handles both passenger and freight trains, are used to calculate track quality degradation trend in a cold climate. The paper describes Trafikverket’s (Swedish Transport Administration) tamping strategy and evaluates its effectiveness in measuring, reporting, and improving track quality. Finally, it discusses the lack of data accuracy and notes the various factors involved in maintenance decisions.
