COVID-19 vs the Great Recession: Practical Data Scope and Methodology for US Rail and Intermodal Freight
Recommendation: Use a single, integrated data scope anchored in asset-based modelling to compare pandemic-driven disruptions against long-run cyclical shifts.
This approach reveals ways to separate supply chain responses by corridor, commodity, asset type.
Scope features:
- Initial pull covers origins, destinations, commodities, asset mix; harmonise time series across states, transcon corridors, ports, major terminals.
- Indicators track chassis availability, engine utilization, rigs counts, road feeder activity, dwell times, throughput; values exposed by demand shifts.
- Integrated content supports real insights into capacity changes, cost per mile, service levels; reliability metrics.
- Single modelling workflow enables shifts between descriptive analytics; part-level forecasting; scenario testing; modeller approach follows frazier administration guidance.
- Data sources include existing administration datasets, carrier chains, terminal records; cross-border flows where applicable.
- Outputs present as modular parts: tables, charts, dashboards suitable for asset-based decision makers; field teams.
- Commodity coverage spans many categories such as perishables, manufactured goods, chemicals, machinery, energy goods, agriproducts; commodities values tracked by corridor.
- Transcon corridor trends compared with road networks reveal sharp shifts in flows across many states; cross-mode comparisons highlight capacity gaps.
- Forecasting relies on integrated statistics plus qualitative inputs; soon updated baselines as new information becomes available.
Implementation steps:
- Define initial scope by asset class, channel, state mix; create shared vocabulary; document abbreviations.
- Assemble data from existing sources: carrier shipments, terminal dwell times, engine utilization, rigs counts, asset inventories, cost per mile; align with policy windows from administration guidelines.
- Build a modular modeller with separate engines for descriptive analysis, scenario forecasting, sensitivity testing; ensure content is reusable across teams.
- Develop indicators: throughput by corridor, part-level utilization, commodity value exposure; track flows by state, origin-destination, chains.
- Output formats: concise dashboards, weekly briefs, quarterly reports; publish content through internal portals for quick access.
Case insights, drawn from initial tests, show:
- Made components reveal real responses: transcon volumes dip sharply during early disruption months; recovery uneven across states; road feeder activity partially fills gaps; asset-based rigs face chassis shortages.
- Frazier-informed simulations suggest downside risks from port congestion; upside arises from inland consolidation improving throughput; rapid shifts towards containerization influence routing choices.
Data Sources and Coverage: Railcar Loads, Intermodal Containers, and Terminal Metrics
Adopt a unified data suite that combines carload volumes; container flow metrics; terminal performance indicators to guide planning.
Key sources include AAR carload series; BTS freight flow datasets; port container counts; also terminal dwell measurements; positive signals from terminal congestion relief.
Scope covers last four quarters; cross-border mexico trade; north-south lines.
Content spans inventory levels; trucking services flows; related middleware metrics.
examining last-year patterns; decline relatively to pre-pandemic baseline; covid-19 effect remains visible; dropping volumes in select corridors.
In inflationary environment, inventory turnover might slow; government policy influences consumer demand; price signals also affect throughput; economy continues to exert pressure; trend remains modest.
Strategy: build models to illustrate linkages among flows, lines, port metrics; compared with baseline to test hypothesis that supply chains respond sluggishly to price shifts; identify leading indicators.
Cross-border mexico flows, pacifics corridors, north-south routes; compare leading indicators to trucking sector performance; note scope limitations.
Recommendation: align data cadence with seasonal patterns; last-quarter revisions; adapt to inflation pressures; maintain timely coverage.
Defining Shock Periods: COVID-19 Peaks, Pandemic Durations, and Recession Phases
Recommendation: adopt a three-phase shock calendar–peaks, duration, recovery; quantify with a shock index derived from weekly movement versus a trend baseline; set minimal thresholds (5–10% deviation) to flag period changes; apply seasonal adjustments to avoid mistaking normal summer variation.
Peaks started in week ended March 21, 2020; movement fell 20–35% below trend; by june 2020 recovery began; july 2020 remained volatile; overall demand variation persisted through late summer.
Pandemic durations varied by corridor; coastal hubs showed different rebound speed; asia exporter redirected toward shorter ocean legs; center ports such as norfolk processed cargo slower; stocks for several product lines tightened, then rebuilt; industry resilience varied by region. During a week with volatility, planners adjust buffers.
Downturn phases reveal cross‑product differences; mostly consumer staples recover faster than durable goods; movement across asia corridors turned increasingly dynamic; electric traction supported faster inland runs; whereas exporters prioritized center hubs such as norfolk; movement across modes showed divergent recovery patterns; measure weekly variation; these insights inform team actions, including capacity buffers, stocks management, modular product adjustments.
Normalization and Metrics: Volume, Utilization, and Seasonal Adjustments
Anchor baseline on april volumes; apply seasonal adjustments; measure real activity via a unified index; prioritize comparing months using normalized metrics rather than raw counts.
- Volume normalization: starting point april; real measures remove weather noise; consumption signals drive demand; smaller markets show fewer loads; rebound visible as consumer spending improves; track comparing months for resilient planning.
- Utilization metric: capacity versus loads; utilization rate equals loads divided by available capacity; chief objective is strong asset use; management actions affect transport speed, fuel costs, savings; consider U.S. railway network capacity constraints in peak hours.
- Seasonal adjustments: apply calendar factors to remove noise from holidays; half of variation tied to harvests, inventory cycles, or maintenance downtimes; adjustments improve comparability across april starting point and later months.
- Inventory and commodity mix: monitor inventories for material flow; track loads by commodity group; transport patterns shift with industrial demand; United States traffic; Mexico cross-border flows; consumption cycles; shifts influence savings, pricing signals.
- Hypothesis testing: compare pre-disruption baseline with current patterns; starting from april anchor; single section approach ensures consistent metrics; respect data gaps, revisions, measurement error.
- Operational guidance: monthly recalibration; monitor volumes, utilization, loads, inventory; fuel cost signals inform savings strategies; management teams respond to shifts in consumption; cross-border flows guide execution priorities for them.
- Measurement presentation: use a single section dashboard; present real values, seasonally adjusted figures, scenario brackets; show april baseline; highlight rebound periods; respect seasonal pattern while exposing structural shifts.
Analytic Frameworks: Time Series, Causal Inference, and Counterfactual Scenarios
Adopt a modular analytic stack; apply Time Series for baseline trends; implement integrated models to support Causal Inference; generate Counterfactual Scenarios to compare paths; quarter reports anchor updates; executive review; federal teams; president.

Causal inference models quantify how operation responds to policy shifts; synthetic control; regression discontinuity; matching; instrumental variables; focus on fewer confounders; robust identification methodology.
Counterfactual Scenarios simulate alternate paths; estimate impact on population; groceries; commodities; container movements; compare completed operation against shutdown episodes; values shift amid federal constraints affecting rail facilities.
Data Quality and Uncertainty: Revisions, Missing Data, and Measurement Gaps

Recommendation: implement quarterly revision protocol with explicit uncertainty bounds for key datasets; publish vintages and confidence intervals with every release.
To capture missing values, establish automated feeds from worldwide railroad data streams; united states terminals in pacific area; electric traction logs. This improves coverage, returns more data, reduces gaps seen in early quarters. Mainly driven by reporting lag in early quarters, revisions often pace toward stability afterward.
Document revisions using vintages; compute uncertainty bands; run scenario analyses covering those possibilities; provide visuals showing outbound flows, inbound movements; related indicators. See figure comparisons for transported volumes by states; average shipments such as milk included.
Address measurement gaps by recording missing items, locations, timing. Those logs support identification of reductions in data coverage; stay alert for shortfalls in outbound streams; personal data sources, missing terminal reports, supplier feeds require tighter capture protocols.
Private channels, such as uber logistics platforms, remain preliminary; validation needed.
