Overview

The prEN 14033-3:2024 standard, developed by CEN (European Committee for Standardization), sets forth general safety requirements for railbound construction and maintenance machines used exclusively on railway infrastructure. This document applies to machines that operate on rails using friction adhesion, including those partially supported on ballast or formation during work activities such as track construction, maintenance, inspection, and operation of signalling and control systems. It addresses significant hazards and risks inherent to such machines based on their intended use or foreseeable misuse. The standard is a vital safety framework harmonizing health and safety practices for railbound machinery across Europe, supporting compliance with the Machinery Directive.

Key Topics

• Scope of Application
  Applies to machines functioning solely on railway tracks, including machines partly supported off rail but involved in rail infrastructure work. Autonomous mobile machines and certain other machinery categories are excluded, per references like CEN/TR 17498:2020.

• Hazard Identification
  Defines significant hazards related to operation, assembly, maintenance, commissioning, cleaning, fault finding, and decommissioning under normal and exceptional conditions (e.g., extreme temperatures, corrosive environments).

• General Safety Requirements

  • Ergonomics and machine profile design for operator safety
  • Prevention measures for derailment and overturning
  • Structural safety of machine frames and couplings
  • Rail wheel suspension and braking system standards
  • Protection against electrical hazards and electromagnetic compatibility
  • Safety protocols for operator cabins, workspaces, high work places, and moving components
  • Warning systems, emergency stops, and visibility enhancements
  • Noise reduction, vibration control, and fire protection features
  • Safe handling of fuel, hydraulic fluids, and hazardous substances

• Additional Functional Safety Measures
  Specific requirements for conveyors, cranes, rail handling devices, ballast chains, dust mitigation, rail profiling machines, and vegetation cutters to mitigate specialized operational risks.

• Verification and Documentation
  Provisions for conformity assessment, testing methods, technical documentation, user instructions, restrictions, maintenance guidance, and warning signage to ensure ongoing compliance and safety.

Applications

prEN 14033-3:2024 serves as a benchmark for safety management in railway infrastructure operations employing railbound construction and maintenance machinery. Stakeholders who benefit from this standard include:

• Rail infrastructure companies needing to ensure machinery safety in track laying, repair, and inspection activities
• Equipment manufacturers designing and certifying railbound construction and maintenance machines
• Maintenance teams and operators following safety instructions and hazard controls aligned with recognized European norms
• Regulatory bodies and safety inspectors evaluating compliance with essential health and safety requirements under EU directives
• Signalling and control system managers incorporating machines into complex railway operations safely

This standard enhances the reliability and safety of railway infrastructure operations, reduces occupational risks, and supports environmental protection through regulated emission and noise controls.
