UIC 505-1

Railway Vehicle Gauge Limits and Clearances

This test method establishes the maximum permissible dimensions and clearance gauges for railway rolling stock to ensure safe passage through railway infrastructure, stations, and tunnels across European rail networks. It defines the envelope within which vehicles must fit to prevent collision with track infrastructure, platforms, and fixed installations. Compliance verification is critical for manufacturers, infrastructure operators, and interoperability authorities to maintain operational safety and network compatibility. Accredited testing ensures objective measurement of vehicle dimensions and systematic verification against gauge requirements, preventing costly delays and safety incidents.

What it measures

  • Vehicle overall width and height envelope
  • Side clearance from track centerline
  • Bogie and wheelset overhang dimensions
  • Buffer and coupling heights
  • Interior and exterior protrusion limits
