AI Analysis: Railway industry diesel fuel consumption by area

Executive Summary

Canada's railway industry diesel fuel consumption, tracked annually from 1986 to 2023, peaked at 2,220,319 thousand litres in 1988 and reached its lowest point of 1,769,604 thousand litres in 2009 during the global financial crisis, recovering to 1,981,186 thousand litres by 2023 — roughly 89% of the historical peak. The dataset spans 60 unique geographic and company series, with Canadian National and Canadian Pacific dominating consumption and exhibiting a near-perfect correlation (r=0.987), indicating their fuel usage moves almost in lockstep. Overall, the long-term trend suggests modest efficiency gains or traffic shifts have prevented a return to late-1980s consumption levels despite partial recovery.

Key Findings

• National railway diesel fuel consumption peaked in 1988 at 2,220,319 thousand litres and has not returned to that level, sitting at 1,981,186 thousand litres in 2023 — approximately 89% of the peak.
• The 2009 global financial crisis caused the single largest year-over-year decline in the dataset, a 14.8% drop to 1,769,604 thousand litres — the only IQR-confirmed statistical outlier across the 38-year period.
• Canadian National and Canadian Pacific railways are the dominant fuel consumers and exhibit an extremely strong positive correlation (r=0.987), meaning their consumption patterns move almost in lockstep over time.
• The distribution of consumption values is heavily right-skewed, with a mean of 156,628 thousand litres more than 8 times the median of 19,064 thousand litres, driven by large aggregate 'Total' categories inflating the upper end.
• The dataset covers 60 unique time series across 12 geographic areas and 5 company categories, with values ranging from near zero to 2,220,319 thousand litres — a spread of over 100,000 times.
• VIA Rail's consumption is strongly correlated with both Canadian National (r=0.906) and Canadian Pacific (r=0.876), suggesting broad industry-wide demand forces drive fuel usage across all major operators.
• The year (REF_DATE) shows a weak negative correlation (r≈-0.20) with company-level consumption, indicating a modest long-term decline or stabilization in fuel use relative to the high levels recorded in the late 1980s.
