Overview
EN 13848-6:2014/FprA1 is a CEN draft amendment to Part 6 of the EN 13848 series: Railway applications - Track - Track geometry quality - Part 6: Characterisation of track geometry quality. The amendment (prA1) updates normative references, refines terminology and notes, and adjusts how track geometry quality classes (TQC) and assessment functions are described and presented. It clarifies use of Power Spectral Density (PSD) methods and adds explanatory notes for high-speed ranges.
Key topics and technical requirements
- Characterisation of track geometry quality: Defines how track geometry quality is quantified and described through assessment functions and indices (e.g., TQIref and Track Quality Classes A–E).
- Track quality classes (TQC): The amendment refines descriptions and presentation of TQC and clarifies how to read percentage-based representations (e.g., “Y1 % of the concerned track section has a TQIref value that is less than X1”).
- Standard deviation thresholds by speed and class: Specifies limit values (standard deviation in mm) for track geometry by speed bands and quality classes. Key values introduced in the amendment include:
- For one set of wavelengths (table example):
- V ≤ 80 km/h: A <1.25 mm, B 1.75 mm, C 2.75 mm, D 3.75 mm
- 80 < V ≤ 120 km/h: A <0.75 mm, B 1.10 mm, C 1.80 mm, D 2.50 mm
- 120 < V ≤ 160 km/h: A <0.65 mm, B 0.85 mm, C 1.40 mm, D 1.85 mm
- 160 < V ≤ 230 km/h: A <0.60 mm, B 0.75 mm, C 1.15 mm, D 1.60 mm
- 230 < V ≤ 300 km/h: A <0.40 mm, B 0.55 mm, C 0.85 mm, D 1.15 mm
- For another wavelength set (alternative thresholds shown in the amendment):
- V ≤ 80 km/h: A <0.90 mm, B 1.25 mm, C 1.95 mm, D 2.70 mm
- 80 < V ≤ 120 km/h: A <0.50 mm, B 0.70 mm, C 1.05 mm, D 1.45 mm
- 120 < V ≤ 160 km/h: A <0.45 mm, B 0.55 mm, C 0.75 mm, D 1.00 mm
- 160 < V ≤ 230 km/h: A <0.40 mm, B 0.50 mm, C 0.70 mm, D 0.90 mm
- 230 < V ≤ 300 km/h: A <0.35 mm, B 0.40 mm, C 0.50 mm, D 0.65 mm
- For all tables: values for V > 300 km/h are listed as “Not available” (NOTE 1).
- For one set of wavelengths (table example):
- High-speed considerations: For speeds >160 km/h, standard deviations within wavelength D2 (and D3) can also be considered, though corresponding values are not yet defined (NOTE 2).
- Power Spectral Density (PSD): The amendment clarifies wording on PSD calculation and requires the PSD calculation method to be specified when alternative methods are used.
- Editorial and normative updates: Adds normative references to EN 13848-5 and EN 14363 and adjusts clause numbering and wording (e.g., “may” → “can” in specific notes).
Applications and users
- Railway infrastructure managers and track engineers for condition assessment and maintenance planning.
- Asset managers and planners to define geometric quality targets and inspection acceptance criteria.
- Test laboratories and vehicle/track interaction analysts using PSD and assessment functions for diagnostics and simulation.
- Standards bodies and procurement teams to reference unified TQC limits in contracts and network specifications.
