Tender WI&VS (Switch measurement and video inspection)
Switch model andapplication of norms: AL, IL and IAL
Short introduction• Two suppliers of loaded switch (and crossing) measurements• Measurements made for the following purposes:
� In control statement (safety)� Contract-management of ProRail with maintenance contractor� Long term maintenance� Contractor (for medium and short term maintenance)
2
• Not operational yet, due to:� It’s new and ambitious� Combination with Video Inspection� Processes by the contractor� Problems with bulk measurements� Complex process (see next slide)� …

ProRail
Short introduction
• Measurements are made by contracted company• Data check is done by ProRail (is the data valid? Is the data delivered according to the contract and specifications?)• Release data (through Irissys) to contractors, etc.• Contractors judge the infra

Norms
13
Complexity of digitizingand applying norms
Current norm
Norms: Gauge in crosssing section
1. Design value track gauge
2. Local speed up to 40 km/h
3. Crossing section with non movable parts
4. Frontpart of crossing
5. Diverging branch
6. Type switch: diverging, equal split, inside single/double slip
14
Not well defined
The IAL for track gauge of the front part of the crossing section (if it’s not movable) for diverging branches of switches with a local speed up to 40 km/h is equal to a nominal value of +12 or -7 mm.

Questions?
Discussion points
• Judgement of data quality and switch quality cannot be split up• The judgement of safety of a switch can and must be done on a much more intelligent way with continuous data
• New norms are needed for loaded switch measurements
