EN 14253
Railway Track Geometry Calculation and Classification
EN 14253 establishes methods for measuring, calculating, and classifying geometric parameters of railway tracks including gauge, alignment, and longitudinal profile. This standard provides quality classifications that determine allowable operating speeds and maintenance priorities for railway lines across Europe. Railway infrastructure operators, maintenance contractors, and network authorities rely on accredited measurement and assessment to ensure safe train operations and optimize maintenance scheduling. Accreditation of testing laboratories guarantees consistent, reproducible measurement methodologies and impartial classification decisions. Proper track geometry monitoring prevents derailments, reduces component wear, and maintains passenger and freight service reliability.
What it measures
- Track gauge (rail-to-rail distance)
- Horizontal and vertical alignment deviations
- Longitudinal profile and gradient parameters
- Twist and cross-level of the track
- Quality classification relative to speed limits
