Canadian National Railway stock closed Q3 earnings day at CA$172.81, roughly flat over the past week and modestly ahead over the past month, even as the headline story sat in the income statement. The railway just posted Q3 2026 basic earnings per share of CA$2.00 on CA$4.77b of revenue, with net income of CA$1.21b, and the share price reaction barely flickered.
For short term traders that might look underwhelming. For anyone thinking in years, not days, the more important question now is how those profits, margins and cash generation stack up against the current valuation and multi year earnings forecasts.

Canadian National Railway: Testing The Growth Engine
The bullish story hangs on Canadian National Railway turning Western corridor spend and Fast Track into durable volume and cost wins.
“The main thing that has to go right is that Canadian National Railway successfully turns Western Canada capacity investments, new commercial agreements and Fast Track savings into durable volume growth and lower unit costs.”
Q3 shows important but partial progress. Revenue ton miles rose 4% and grain and fertilizer volumes climbed double digits, which lines up with the Western capacity bet. The adjusted operating ratio improved 40 bps and Fast Track savings reached roughly US$120m year to date, along with record fuel efficiency, which backs the unit cost ambition.
