EN 13848-2 Track Geometry Measurement by Inertial Methods
The European Standard EN 13848-2 provides a comprehensive framework for measuring track geometry using inertial methods. This standard is particularly relevant in the railway and transportation testing sector, where ensuring the safety and reliability of rail infrastructure is paramount.
Track geometry plays a critical role in maintaining the integrity of the railway network. Irregularities such as unevenness, misalignment, or wear can lead to increased maintenance costs, reduced train speeds, and potentially dangerous conditions for passengers and freight. Inertial methods offer a precise way to assess these parameters without requiring extensive track downtime.
The standard defines several key geometrical parameters that are crucial for maintaining the safety of railway operations:
- Alignment
- Elevation
- Level
- Width
- Track gauge
- Curvature and superelevation
These parameters are measured using inertial sensors installed on a specialized vehicle that traverses the track. The data collected is then analyzed to ensure compliance with specified tolerances as defined by EN 13848-2.
The process begins with thorough preparation of the track section to be evaluated. This includes ensuring the area is free from debris and other obstructions that could interfere with the measurements. Once the vehicle equipped with inertial sensors has traversed the track, it processes the data in real-time or post-processing depending on the setup.
The results are then compared against the acceptance criteria provided by EN 13848-2 to determine if any corrective action is required. Any deviations from the specified tolerances can indicate areas that need attention for maintenance or repair.
Compliance with this standard ensures not only the safety and reliability of railway operations but also helps in meeting regulatory requirements set forth by various national and international bodies, including UIC (Union Internationale des Chemins de Fer).
The precision and repeatability offered by inertial methods make it an ideal choice for regular track inspections and maintenance planning. This ensures that any issues are identified early, minimizing disruptions to service and enhancing overall rail safety.
