The Preemption tool is the first technology tailored for managing preemption equipment inventory, maintenance, inspections, and replacements. Use Preemption in tandem with our other data-driven Signal Management solutions for full visibility of signal-related assets. 


  • Planned Maintenance: Create maintenance schedules, identify recurring maintenance tasks, gauge asset performance, and proactively plan for repairs.
  • Repeating Work Orders: Group the assorted, routine tasks—such as maintenance, inspection, and testing—within a single work order. Then schedule that work order to repeat at your preferred interval.
  • Guided Inspections: Populate the ordered fields, attach notes and photos, and schedule necessary follow-up tasks on the spot.
  • Detailed Records: Instantly see the asset's entire event and inspection history. Use that data when planning budgets and forecasting service life.
  • Risk & Business Risk Exposure (BRE): These scores help you prioritize work and allocate your budget to address higher risk assets. The risk score is a number from 1 to 25 and is based on an asset's Probability of Failure and its Consequence of Failure. Calculating Risk is available for all asset types and Equipment.

Asset Details

Intelligently ordered fields lead users through inspections, making sure every piece of essential information gets captured. Use your data to calculate current condition, anticipate future condition, and predict remaining service life.
