Wabtec makes the brakes, engines and electronics that let freight trains and metro cars move and stop safely, then sells the parts, rebuilds and software that keep them working for decades. The steady repair-and-rebuild half pays the bills; the surge is in new locomotives for railroads abroad and in recently bought sensing and inspection businesses. No single customer is even a tenth of sales.

Equipment — locomotives & mining drives
New freight locomotives, plus the electric drive systems inside the largest mining haul trucks. Sales grew 12% in 2025 and far faster through the first half of 2026; the multi-year order book passed $30 billion by mid-2026, up 42% in a year.
Competes with SD70ACe-T4 locomotives (Progress Rail (Caterpillar)) · Export locomotives (CRRC) · Ultra-class haul truck drive systems (Komatsu)
In plain English
A freight locomotive is the pulling machine at the head of a heavy train — a diesel engine that makes electricity, and electric motors that turn that into grip at the wheels. Wabtec builds them in Texas, Pennsylvania, Brazil and India, and sells the same drive technology to mining companies for their biggest haul trucks.
Railroads order years ahead and pay as units are handed over, so the revenue showing up now was agreed long ago. Much of the recent buying sits outside North America — Kazakhstan, Brazil, India, Australia — and delivery talks already stretch to 2028. Tariffs on imported parts and chip supply are the things that can spoil a build slot.
KTZ Locomotive & Service Program
Kazakhstan's national railway ordered $4.2 billion of locomotives plus years of fleet maintenance in September 2025 — the largest order in Wabtec's history. Sales to the region actually fell in 2025, so almost all of this money is still ahead.
Competes with Locomotive exports (CRRC) · Regional fleet supply (Transmashholding) · EMD export platform (Progress Rail)
In plain English
One order, larger than anything in the company's past. Kazakhstan's state railway — the operator carrying traffic on the Trans-Caspian trade route — agreed to buy Evolution Series locomotives and to have Wabtec look after them for years afterwards.
The cash arrives slowly. A contract like this pays out as units roll off the line and as maintenance hours get worked, spread across several delivery years, with some fabrication and assembly done locally in Kazakhstan while the engine controls stay with Wabtec. It is also business that leans on one government's budget and one region's politics holding steady.
Freight Components
Brakes, wheel trucks, couplers and heat exchangers sold to the builders of new freight wagons. Revenue barely moved in 2025 at $1.59 billion, and the North American wagon build is expected down roughly a fifth again in 2026 — the cyclical soft spot.

In plain English
Every freight wagon behind a locomotive needs brakes that clamp, a steel frame on wheels underneath, and a coupler holding it to the next wagon. Wabtec makes those parts and sells them to the factories assembling new wagons and to railroads replacing worn ones.
So this line rises and falls with how many wagons North America decides to build — and that number dropped hard in 2025 with another decline expected in 2026. Wabtec is also deliberately walking away from low-margin products here, which subtracts sales but leaves a better mix behind. Selling engines and parts to industrial and power plants takes up some of the slack.
Locomotive Services & Modernizations
The single biggest line: parts, overhauls, maintenance contracts and full rebuilds of locomotives railroads already own. It grew just 1.2% in 2025 as rebuild deliveries slipped, and management expects it back to growth in the second half of 2026.
Competes with Locomotive modernization (Progress Rail (Caterpillar)) · In-house back shops (Class I railroads) · Brake component overhaul (Knorr-Bremse)
In plain English
Rebuilding a locomotive is like re-engining and re-wiring an old truck instead of buying a new one: the frame stays, the tired guts come out, and the machine goes back to work for another long stretch at a fraction of the price. Wabtec does that work, and sells the brake shoes, spare parts and long-term maintenance deals that keep fleets moving in between.
The demand is already sitting on the tracks — more than a quarter of North America's working locomotives are over twenty years old. Railroads pay per programme; Union Pacific's latest runs to about $1.2 billion. Wabtec does not win them all: Norfolk Southern sent thirty-three units its way and ninety-six to a rival.
Transit Aftermarket
Spare parts and overhauls for passenger vehicles — metro cars, commuter and high-speed trains, light rail, buses. $1.74 billion in 2025 and the faster-growing half of the passenger business, rising and falling with public transport budgets.
Competes with Rail Vehicle Systems aftermarket (Knorr-Bremse) · Fleet services & maintenance (Alstom) · Aftermarket parts and service (CRRC)
In plain English
Passenger trains wear out on a predictable clock: brake pads thin, door mechanisms stiffen, couplers need rebuilding. A transit authority either keeps spares on the shelf or hires someone to do the overhauls, and Wabtec sits on both ends of that — it makes the parts and it does the work.
Because the payer is a public body or the operator it hires, the money follows tax budgets and how many people ride, not how much freight moves. New York City Transit, for instance, bought about fifty million dollars of brake and coupler servicing. Something over half of everything Wabtec sells into passenger rail is this kind of repeat work.
Transit Original Equipment
Brake systems, doors, air conditioning, couplers and passenger displays fitted into brand-new metro and mainline passenger cars. $1.39 billion in 2025; across the whole passenger business, orders due within a year reached $2.57 billion by early 2026.

In plain English
When a factory builds a new subway train or regional coach, it does not make everything itself. It buys the braking system, the sliding doors, the air conditioning on the roof, the coupler at each end and the screens announcing the next stop — and Wabtec sells all of those to the car builders, plus the sliding doors that guard station platforms.
Work arrives as multi-year vehicle programmes, so one win feeds revenue for years: Siemens Mobility bought seventy million dollars of passenger information systems for ninety Munich commuter trains, and a Paris rail project fifty-five million dollars of platform doors. Buying Dellner in 2026 added the connections between carriages to the shelf.
Digital Intelligence
Train-control software and trackside sensors: remote handling of locomotives spread along a train, fuel-saving driving software, braking that stops a train automatically. Sales grew 31% in 2025 and nearly doubled by mid-2026 — the jump came from acquisitions, not from selling more of the old products.

In plain English
Trains now report on themselves. Wabtec's electronics sit in the cab and beside the rails: one system lets the driver at the front control engines placed in the middle and at the tail of a very long train; another works out the most fuel-efficient way to drive a route; another watches speed and signals and applies the brakes itself if the crew misses one. Small boxes clamped to the rail count axles rolling past so a signaller knows which stretch is occupied.
Railroads pay for the hardware, the fitting and the ongoing licences, and the enormous fleet Wabtec already built is the natural place to sell them.
Inspection Technologies
Testing gear that looks inside metal without cutting it — ultrasound, X-ray and camera probes. Bought from Evident for about $1.8 billion in 2025, it carried Wabtec out of rail into aerospace, energy and factory inspection.

In plain English
Ultrasound for machines. These instruments check whether a turbine blade, a weld or a pipe has a crack hidden inside: probes that push sound or X-rays through metal, and tiny cameras on flexible cables that reach where a hand cannot.
Wabtec paid roughly $1.8 billion for the business in 2025 — its largest purchase since buying GE's locomotive arm — from Evident, previously the scientific instruments side of Olympus. Buyers are aerospace, energy and industrial firms that must inspect ageing equipment on a schedule, so the buying repeats as those deadlines come round. Management says each sale earns more than the Wabtec average, but costs more to go out and win.
