Railcar vs. Locomotive — What's the Difference?
By Tayyaba Rehman & Urooj Arif — Updated on May 17, 2024
A railcar is a self-propelled railway vehicle used for passenger or freight transport, while a locomotive is a powerful engine that pulls or pushes a train of railcars.

Key Differences
A railcar is a railway vehicle that is self-propelled and often used for passenger transport on smaller or regional lines. It combines the functionality of both an engine and a passenger or freight car, enabling it to operate independently without needing a separate locomotive. A locomotive, on the other hand, is specifically designed to provide the motive power for a train. It does not carry passengers or freight directly but pulls or pushes a series of railcars or wagons. This makes it a central component in the operation of larger, more complex train systems.
Railcars often have limited power and are designed for lower-speed operations, making them ideal for urban or regional transit systems. Locomotives, however, are built for higher speeds and longer distances, equipped with more powerful engines to handle rigorous demands.
While railcars serve a dual function by carrying passengers or goods and providing propulsion, locomotives are dedicated to propulsion alone, requiring additional railcars to fulfill their transport purpose.

Compare with Definitions
Railcar
A self-propelled railway vehicle used to transport passengers.
The railcar departed from the station on its scheduled route.
Locomotive
An engine at the front or rear of a train.
The locomotive pushed the passenger cars through the mountain pass.
Railcar
A railway vehicle combining engine and carriage.
The railcar’s compact design makes it ideal for regional lines.
Locomotive
A rail vehicle that does not carry passengers or cargo directly.
The locomotive detached from the train after reaching the yard.
Railcar
A single-unit train that operates independently.
The railcar provided a direct service to the suburban areas.
Locomotive
A unit that moves railcars or wagons on tracks.
The diesel locomotive idled at the platform, ready for departure.
Railcar
A lightweight rail vehicle often used on less busy routes.
The railcar was perfect for the town’s modest passenger numbers.
Locomotive
A powerful engine used to pull trains.
The locomotive hauled a dozen freight cars across the country.
Railcar
A vehicle that can travel on both rail tracks and roads.
The dual-mode railcar smoothly transitioned from tracks to road.
Locomotive
A locomotive or engine is a rail transport vehicle that provides the motive power for a train. If a locomotive is capable of carrying a payload, it is usually rather referred to as a multiple unit, motor coach, railcar or power car; the use of these self-propelled vehicles is increasingly common for passenger trains, but rare for freight (see CargoSprinter and Iron Highway).
Railcar
A railcar (not to be confused with a railway car) is a self-propelled railway vehicle designed to transport passengers. The term "railcar" is usually used in reference to a train consisting of a single coach (carriage, car), with a driver's cab at one or both ends.
Locomotive
A self-propelled vehicle, usually electric, diesel, or steam-powered, for pulling or pushing freight or passenger cars on railroad tracks.
Railcar
A railroad car.
Locomotive
A driving or pulling force; an impetus
"The US could no longer serve as the locomotive for the world economy" (George Soros).
Railcar
(rail) A self-propelled railway vehicle for passengers, similar to a bus.
Locomotive
Of, relating to, or involved in locomotion.
Railcar
(rail) A powered single railway vehicle designed for passenger transport, with a driver's cab in both ends; Not to be confused with motor coach/motorcar, which is a powered railway vehicle capable to haul a train.
Locomotive
Serving to put into motion or propel forward
"It may be that the founding fathers overestimated the locomotive force of the collective and mutual self-interest" (Ian Davidson).
Railcar
(Only in Canada and US) Any unpowered railway vehicle
Locomotive
Able to move independently from place to place.
Railcar
A wheeled vehicle adapted to the rails of railroad;
Three cars had jumped the rails
Locomotive
Of or relating to a self-propelled locomotive.
Locomotive
Of or relating to travel.
Locomotive
(rail transport) The power unit of a train that pulls the coaches or wagons.
Rolling stock
Locomotive
(rare) A traction engine.
Locomotive
(slang) A cheer characterized by a slow beginning and a progressive increase in speed.
Locomotive
(archaic) Any of various early road vehicles, steam-powered, etc., forerunners of the modern car.
Locomotive
(economics) A country which drives the world economy by having a high level of imports, such as the United States.
Locomotive
Of or relating to locomotion.
Locomotive
Of or relating to the power unit of a train which does not carry passengers or freight itself.
Locomotive
Moving, or capable of motion.
Locomotive
Moving from place to place; changing place, or able to change place; as, a locomotive animal.
Locomotive
Used in producing motion; as, the locomotive organs of an animal.
Locomotive
A locomotive engine; a self-propelling wheel carriage, especially one which bears a steam boiler and one or more steam engines which communicate motion to the wheels and thus propel the carriage, - used to convey goods or passengers, or to draw wagons, railroad cars, etc. See Illustration in Appendix.
Locomotive
A wheeled vehicle consisting of a self-propelled engine that is used to draw trains along railway tracks
Locomotive
Of or relating to locomotion
Locomotive
A vehicle designed solely for providing motive power on railways.
The steam locomotive is a classic symbol of industrial progress.
Common Curiosities
What are locomotives primarily used for?
Locomotives are used for long-distance travel and hauling heavy freight.
What kind of routes are best suited for railcars?
Railcars are best suited for urban, suburban, and regional routes with moderate traffic.
What are the typical uses of railcars?
Railcars are commonly used on short-distance, regional routes with lower passenger or freight volumes.
Do locomotives carry passengers or goods?
No, locomotives only provide the motive power and do not carry passengers or goods directly.
What is a railcar?
A railcar is a self-propelled railway vehicle used for carrying passengers or freight.
What is a locomotive?
A locomotive is an engine designed to provide the motive power for a train.
How does a railcar differ from a locomotive?
A railcar can move independently and carry passengers or goods, while a locomotive needs to pull or push railcars.
Are locomotives used for passenger trains?
Yes, locomotives are used to pull or push passenger railcars on long-distance routes.
Which is more economical for short trips, a railcar or a locomotive?
A railcar is more economical for short trips due to its self-propelled nature and lower infrastructure needs.
Which is better for high-speed travel, a railcar or a locomotive?
Locomotives are better suited for high-speed travel due to their greater power and design for long-distance routes.
