About

Alicia Sanchez is a leading researcher in railway infrastructure engineering, with a primary focus on track geometry measurement and maintenance optimization. Her most-cited work, "Estimating the Accuracy of Track-Surveying Trolley Measurements for Railway Maintenance Planning" (2016, 36 citations), addresses a critical challenge in European railway policy: ensuring the reliability of track inspection data used for maintenance decisions. Sanchez’s research bridges the gap between European standardization requirements (CEN) and practical measurement uncertainties, providing infrastructure managers with validated methodologies for assessing trolley-based survey accuracy. Her contributions are particularly impactful for the European Union’s push toward interoperable, high-performance rail networks, as they directly inform cost-effective maintenance planning and safety compliance. By quantifying measurement errors and proposing calibration frameworks, Sanchez has helped reduce the risk of undetected track defects while optimizing resource allocation. Her work is widely cited by both academic researchers and railway engineers, reflecting its dual relevance to theoretical metrology and applied infrastructure management. Sanchez continues to shape the field through her rigorous analysis of measurement systems, making her a key figure in advancing data-driven railway maintenance strategies across Europe.
