Rail Signaling & Wayside Equipment worked example

Firmware Verification Load with verification bench connected load of 30 kW: a worked example

This scenario runs the firmware verification load calculation on the strong side: verification bench connected load of 30 kW, with every other input held at its documented default. Use it when firmware verification load in rail signaling and wayside equipment is up for an upgrade and you want a defensible savings story.

The inputs for this scenario

  • Verification bench connected load: 30 kW (raised for this scenario; the documented default is 12)
  • Firmware verification runtime per batch: 8 hr (unchanged)
  • Blended plant electricity rate: 0.12 $ / kWh (unchanged)
  • Signaling modules verified in run: 1,000 units (unchanged)

Working through the calculation

  • Applying the documented formula (Total firmware verification load energy cost = firmware verification load connected load × firmware verification load runtime × blended electricity rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 240 kWh for firmware verification load energy used, the number this scenario is built around.
  • At this operating point the engine returns 28.8 $ for total firmware verification load energy cost.
  • At this operating point the engine returns 0.03 $ / piece for energy cost per kwh.
  • At this operating point the engine returns 3.6 $ / hr for hourly firmware verification load energy cost.

How this compares with the baseline

  • Against the tool's baseline example, where verification bench connected load sits at 12 kW and the headline result is 96 kWh, this scenario comes in 150% above the baseline at 240 kWh.
  • Use it when costing the firmware validation and burn-in stage of a signaling build, or when allocating test-lab energy to a specific module program. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Firmware verification load energy used: 240 kWh (headline result)
