Since Cat® diesel engines first powered the world’s railways in the 1930s – and for thousands of locomotive installations around the world – builders and operators have found very compelling reasons to specify Cat diesel engines. Today, Caterpillar® is the single most experienced name in power. Over the decades, Caterpillar® engineers have designed diesel engines for the toughest railway operating environments. These power solutions have included engines for all rail applications - driving traction alternators, auxiliary power, head end power, diesel hydraulic, and diesel mechanical. These engines serve our customers well with high reliability, durability, exceptional life, and low operating costs. Caterpillar® engines are engineered for life.

Optional cooling packages are also available.
- Locomotive Engines
Caterpillar manufactures diesel engines for locomotive traction, ranging from compact switcher engines to high-horsepower solutions for freight and passenger applications. - Emissions Standards
Our engines are engineered to meet stringent global emissions standards, including U.S. EPA Tier 4 Final and EU Stage V, helping reduce environmental impact while maintaining performance. - Battery-Electric Technology
Through Progress Rail, Caterpillar is advancing battery-electric locomotive solutions, supplying major rail operators such as Union Pacific. - Factory Rail
Specialized Cat drives and engines are designed for industrial rail operations that run continuously with frequent start-stop cycles. These solutions can be combined with battery storage to support low- or zero-emission operation. - Maintenance of Way (MOW)
Cat engines power a wide range of railway maintenance equipment, including tamping machines, ballast cleaners, and rail grinders—ensuring reliability in critical infrastructure upkeep. - Dynamic Energy Transfer (DET)
Caterpillar’s Dynamic Energy Transfer system enables efficient energy transfer to battery-electric or diesel-electric equipment, improving overall efficiency and supporting hybrid operations.
- Powertrains
Caterpillar offers integrated powertrain solutions that combine diesel engines with transmissions, specifically designed to meet the demands of the rail industry. - Control Systems
Advanced electronic control systems are developed for diesel-electric locomotives, including traction inverters and start-stop technologies that enhance efficiency and performance. - Support
Through Progress Rail and its global network of authorized dealers, such as Avesco, Caterpillar provides comprehensive support, including parts availability and maintenance services for rail engines.
Caterpillar® offers a complete line of Cat diesel engines coupled to modern, highly efficient, Cat transmissions.
This modern alternative to traditional locomotive propulsion offers lower initial cost and higher efficiency than either diesel-electric or diesel-hydraulic power – a significant advantage in life cycle costs.
If your project is 1200 kW (or 1500 HP) or below, ask us about this unique solution to power a rail vehicle for less initial cost and less operating cost.
- Locomotive
- Shunter
- Switcher
- Maintenance-of-way
- Utility etc.
Each year, Caterpillar supplies hundreds of thousands of engines to more than a thousand of the world’s best manufacturers of equipment in all industries.
