Wabtec and the Rail FieldThin moat

Caterpillar (CAT) — moat facet

Caterpillar's rail business earns about 4.7% on $3.4 billion of sales, after a $925 million write-down, against six named rivals.

Rail is where Caterpillar's competitive position is weakest by its own accounting. Its rail competitors are Wabtec, Greenbrier, Voestalpine, Vossloh, Alstom and Siemens Mobility1. In 2022 it recorded a $925 million goodwill impairment related to "a lower outlook for the company's locomotive offerings"2, and in the fourth quarter of 2025 higher restructuring costs were mainly write-downs in the value of inventory in the Rail division3.

Four cents of profit per dollar.

The margin tells the rest. When Caterpillar moved Rail from Power & Energy to Resource Industries on 1 January 2026, it recast 2025: Resource Industries' sales rose from $12,474 million to $15,920 million and its profit from $1,988 million to $2,151 million45. That implies Rail had about $3,446 million of sales and $163 million of profit, a margin of about 4.7%6. The rest of Caterpillar's machine businesses earn three to four times that.

Rail is sold largely directly: locomotives are among the products Caterpillar sells to end customers through its own sales forces7, so the dealer moat does not help.

There are signs of recovery. Rail sales were $883 million in the second quarter of 2026, up 15%8, and dealer-reported sales to users rose 272%9.

The move into Resource Industries also changed what the company reports. Transportation, previously a Power & Energy application covering rail and marine, disappeared; marine and on-highway engine product support moved into the Industrial application10. Rail is now reported as an industry line within Resource Industries.

This is a rival field in which Caterpillar competes without its usual advantages. Rail's margin, which can now be read only inside Resource Industries, is the measure: a business earning under 5% on $3.4 billion of sales either needs to improve or to be sold.

Moat trajectory: Holding steady

Rail sales +15% in Q2 2026 after 2025 inventory write-downs.

Rail sales, latest quarter
$883M, +15% (Q2 2026)

The weakest business against its rivals; margins still near 5% after the recovery would argue for selling it.
