PSR: What Precision Scheduled Railroading Did
Precision scheduled railroading defined from Union Pacific and CSX filings, what it changes in a network, and how FY2025 operating ratios compare on one basis.

PSR Changed How Trains Run; the Operating Ratio Records the Result
Precision scheduled railroading (PSR) made its biggest gains early, and the same label now sits beside very different results. So the question for any railroad is what PSR did to its operating ratio, operating expenses as a share of revenue, and whether the change held.
Union Pacific began implementing PSR in late 2018. Its 2021 Investor Day transcript (4 May 2021) names three aims: point-to-point schedules in place of hub-and-spoke routing, higher asset turns (more use from each locomotive, crew and yard), and cost take-out when volume is weak. CSX’s FY2025 10-K says executing its scheduled service plan reduces costs and supports free cash flow. The wording varies by railroad; the common thread is handling each car fewer times on a more predictable train plan.
FY2025 Operating Ratios After PSR
The five ratios still sit far apart, and each railroad’s reported and adjusted ratios can differ by up to 2.9 points. The table shows both for the year ended 31 December 2025 (CSX’s derived from its operating margin):
| Company | Reported OR | Adjusted OR | Basis note |
|---|---|---|---|
| Union Pacific | 59.8% | 59.3% | PSR implementation from late 2018 |
| Canadian Pacific Kansas City | 62.8% | 59.9% core adjusted | ”Core adjusted” is the company’s own measure |
| Canadian National | 61.9% | 61.7% | Both printed |
| Norfolk Southern | 64.2% GAAP | 65.0% | Adjusted sits above GAAP; GAAP −220 bps YoY |
| CSX | 67.9% implied | 66.8% implied | 100% minus filed operating margin |
Union Pacific cited 58.5% adjusted OR in 2020 at its 2021 Investor Day, with volumes down 13% on 2018. Its FY2025 adjusted figure is close to that level: the large step came early, and the ratio has held near it since.
Norfolk Southern: A 220 bps Year
Norfolk Southern’s ratio improved through cost rather than extra traffic. Its GAAP ratio was 220 bps better than FY2024’s 66.4%, while its adjusted ratio improved 80 bps from 65.8%, so a figure means little without its basis. Total units rose only 0.1%, and the company reported productivity savings above $215m in FY2025. Intermodal traffic (containers and truck trailers on rail) was 57.7% of its units, but merchandise (mixed carload freight such as chemicals, metals and autos) supplied 63% of revenue.
CSX uses the same scheduled-service vocabulary on a network where intermodal is 48% of units. Density, geography and traffic mix are why an operating label does not map one-to-one onto an operating ratio.
What Is Left After the Easy Wins
After the easy savings, the ratio moves more on pricing, mix and capital than on the schedule. Early programmes took those savings: longer trains, closed yards, fewer locomotives when carloads fell. Industry operating margins rose from roughly 20% in the early 2000s towards ~40% by 2021, according to a public railroad summary from Vontobel (a secondary source).
From there the levers are core pricing on merchandise renewals (see RPU mix effects); intermodal density, which helps only if lane pricing holds against trucks (intermodal economics); and capital spending, where the test is return on invested capital against its cost.
Worked Example: Basis Points to Dollars
Take an illustrative mid-size Class I railroad (the top revenue tier of North American freight carriers): 5.5m units at $2,400 revenue per unit gives $13.2bn of revenue, run at a 61.0% operating ratio. Apply an improvement the size of Norfolk Southern’s FY2025 GAAP move:
| Step | Calculation | Result |
|---|---|---|
| Starting OR | 61.0% | |
| Ending OR | 61.0% − 2.2 points | 58.8% |
| Expense saved | 2.2% × $13.2bn revenue | ~$290m of operating income |
Each basis point is a fixed share of revenue, so the same move is worth more on a larger network. A late-stage programme that shaves only a point or two still shows in the income statement.
Where PSR Meets Valuation
PSR does not enter a valuation directly. Its results do: the level of the operating ratio, the return on capital and the free cash flow once the ratio settles. Read a railroad’s ratio history on one basis to judge how much of the change is finished.
The operating ratio fades year by year off volume, revenue per unit and capex, feeding a value per share checked against return on capital.
The Excel model is the primer's railroad build live across 11 sheets: revenue from volume and revenue per unit, an operating ratio that fades year by year, a valuation for a mature compounder and an improvement story, a margin bridge, return on capital against the cost of capital, free cash flow and capital returns, and a sensitivity grid. Change the operating ratio path or capex and the value moves.
Frequently Asked Questions
- What is precision scheduled railroading (PSR)?
- Union Pacific describes PSR as scheduled point-to-point service, asset utilisation and cost control, implemented from late 2018 per its 2021 Investor Day materials. CSX ties its scheduled service plan to lower costs and free cash flow in its FY2025 10-K. PSR is an operating model; no single accounting line measures it.
- Did PSR get railroads below a 60% operating ratio?
- Union Pacific cited a 58.5% adjusted operating ratio for 2020 at its May 2021 Investor Day; its FY2025 adjusted ratio was 59.3%. Canadian Pacific Kansas City reported 59.9% core adjusted for FY2025. CSX, also a scheduled-service railroad, had an implied adjusted ratio of 66.8%. The 60% line is a sorting convention. The same operating label sits beside very different ratios, because density and traffic mix matter as much as the schedule.
- Which Class I railroad improved its operating ratio most in FY2025?
- Among the four that print an operating ratio, Norfolk Southern moved furthest on reported figures: 64.2% GAAP in FY2025 against 66.4% in FY2024, a 220 basis point improvement. On its adjusted line the move was 80 basis points, from 65.8% to 65.0%. Canadian National improved 150 basis points on reported figures and Canadian Pacific Kansas City 160.
- What PSR gains are left once a network has adopted it?
- Early PSR gains came from consolidating trains, closing yards and running fewer locomotives, often while volumes were falling (Union Pacific volumes were down 13% versus 2018 when its 2020 ratio was cited). Once those steps are taken, further change in the ratio depends more on pricing, traffic mix and capital spending than on another reorganisation of the schedule.
