pistevirhe

Pistevirhe, also known as a track error or track misalignment, refers to a condition in which the physical track of a railway deviates from its intended alignment. This deviation can occur due to various factors, including natural causes such as soil movement, erosion, or landslides, as well as human-induced factors like construction errors, maintenance issues, or improper track design. Pistevirhe can lead to several problems, including derailments, reduced train speeds, increased wear and tear on railway equipment, and potential safety hazards for passengers and crew.

The causes of pistevirhe can be categorized into two main groups: natural and artificial. Natural causes include geological processes such as subsidence, landslides, and soil erosion, which can alter the track's alignment over time. Artificial causes encompass human errors during construction, inadequate maintenance, and improper track design. Additionally, environmental factors like heavy rainfall, snow, or temperature changes can exacerbate pistevirhe by causing soil expansion or contraction.

Detecting and correcting pistevirhe is crucial for maintaining safe and efficient railway operations. Various methods are employed to identify track misalignments, including visual inspections, automated track geometry measurement systems, and manual surveys. Once detected, corrective actions may involve realigning the track, repairing damaged sections, or implementing preventive measures to mitigate future misalignments. Regular maintenance and monitoring are essential to address pistevirhe promptly and minimize its impact on railway infrastructure and operations.
