Railcar Loading Time at 23% non-loading time allowance: a worked example

What does the result look like when non-loading time allowance reaches 23%? The full calculation is worked below with real intermediate numbers. Use it when a logistics coordinator or plant manager needs to schedule railcar loading windows, plan crew coverage, or verify that the loadout system can handle the rail shipment schedule.

The inputs for this scenario

  • Railcar net capacity: 100 tons (unchanged)
  • Effective loadout rate: 150 tons / hr (unchanged)
  • Non-loading time allowance: 23 % (raised for this scenario; the documented default is 20)

Working through the calculation

  • Applying the documented formula (Base loading time = railcar net capacity / effective loadout rate x 60 (minutes)) to the inputs above produces each figure below.
  • At this operating point the engine returns 0.82 min for total loading time, the number this scenario is built around.
  • At this operating point the engine returns 0.67 min for base fill time.
  • At this operating point the engine returns 23 % for non-loading allowance.
  • At this operating point the engine returns 150 tons / hr for effective loadout rate.

How this compares with the baseline

  • Against the tool's baseline example, where non-loading time allowance sits at 20% and the headline result is 0.8 min, this scenario comes in 2.5% above the baseline at 0.82 min.
  • A figure at this level is achievable when non-loading time allowance is genuinely sustained, not just peaked for a shift. It assumes a steady effective rate; in practice venting, surge bins emptying, and gate adjustments make the real fill time lumpy, and the allowance is only as good as your estimate of non-loading activities.

Results at a glance

  • Total loading time: 0.82 min (headline result)
  • Base fill time: 0.67 min
  • Non-loading allowance: 23 %
  • Effective loadout rate: 150 tons / hr
