You're standing on a platform. A massive, steel beast roars into the station, hissing air brakes and squealing metal. You look up at the cab window and see someone at the controls. What do you call them? Honestly, it depends entirely on where you are standing and what kind of tracks are under your feet.
Most people just say "train driver." It’s simple. It’s accurate. But if you’re in the United States, calling someone a train driver might get you a polite correction or a confused look. In the U.S. and Canada, the person pulling the throttle is almost always the locomotive engineer. This isn't just a fancy title for a resume; it’s a legal and historical distinction that dates back to the dawn of the steam age.
Wait. It gets more complicated.
The world of rail terminology is surprisingly deep. You’ve got motormen, operators, drivers, and engineers. If you’re in the UK, "driver" is the king of terms. If you’re on a subway in New York City, you’re looking at a "train operator." If you’re talking about the history of the Underground in London, you might hear "motorman."
Let’s break down what is a train driver called and why these names actually matter to the people who do the job.
The Engineer vs. The Driver: A Global Divide
In the United States, the term locomotive engineer is the gold standard. These are the folks who manage the massive diesel-electric engines hauling miles of freight across the Midwest or navigating the Northeast Corridor for Amtrak. To become an engineer in the U.S., you don’t just learn to steer. You have to understand the physics of a 20,000-ton train.
Think about the weight.
Stopping a freight train can take over a mile. The engineer has to calculate grade, curvature, and weather conditions constantly. Because of the technical complexity involving the engine itself, the term "engineer" stuck. They aren't just "driving" a vehicle; they are managing a mobile power plant.
Across the pond, things change. In the United Kingdom, Australia, and much of the Commonwealth, the term is simply train driver. It’s straightforward. Whether it’s a high-speed InterCity or a local commuter rail, the person in the cab is the driver. According to the Associated Society of Locomotive Engineers and Firemen (ASLEF)—which is the main trade union for these workers in the UK—the formal title remains "train driver," though their own union name proves that the "engineer" terminology used to be much more common globally.
Why Do Subways Use Different Names?
If you go underground, the vocabulary shifts again. Most rapid transit systems—like the "L" in Chicago or the London Underground—don't use the term engineer.
They use Train Operator.
Why the switch? Mostly because the job changed. On a traditional heavy rail line, the engineer or driver is responsible for a lot of manual control. On a modern subway or metro system, much of the heavy lifting is done by computers. The person in the front is there to monitor systems, operate the doors, and take over if the Automated Train Operation (ATO) fails.
In some older systems, you might still hear the term motorman. This specifically referred to the person operating an electric motor rather than a steam engine. You’ll still find "Motorman" used in some transit authority bylaws, even if the public-facing signs say "Operator."

The Roles You Might Confuse With a Driver
It’s a common mistake to think everyone working on a train is a driver.
- The Conductor: This is the big one. In North America, the conductor is actually the "boss" of the train, not the engineer. The engineer handles the movement, but the conductor handles the paperwork, the cargo, and the crew. If it’s a passenger train, they handle you.
- The Fireman: You won't see these on your morning commute anymore. Historically, the fireman was the person who shovelled coal into the furnace. On modern heritage steam lines, the fireman is still essential. No steam, no movement.
- The Brakeman: Another ghost of the past. Before automatic air brakes, these people literally ran along the tops of moving cars to turn manual brake wheels.
The Technical Reality of Being a Locomotive Engineer
Let’s get into the weeds for a second. If you want to know what is a train driver called in a professional setting, you have to look at the certifications. In the U.S., the Federal Railroad Administration (FRA) handles the licensing. You aren't just "Bob the driver." You are a Certified Locomotive Engineer.
The training is grueling.
Most people start as a conductor. You spend years on the ground, throwing switches and walking tracks in the rain. Only after you’ve proven you won't get crushed by a coupling do you get to apply for the engineer program. This involves months of classroom time learning air brake physics and "train handling."
Train handling is an art form. Imagine a string of 100 cars. When the engineer starts the engine, the front moves, but the back doesn't—not yet. There is "slack" in the couplers. If the engineer jerks the throttle, that slack snaps like a whip. By the time it reaches the 100th car, it can be powerful enough to snap a steel knuckle or derail the train.
This is why "engineer" is the preferred term in heavy freight. It’s about managing forces that most of us can’t even wrap our heads around.
Regional Quirks: What to Call Them Abroad
If you’re traveling, the name changes with the language, but the respect for the role stays the same.
In France, they are the Conducteur de train. Don't let the name fool you; this is the driver, not the person checking tickets. In Germany, you’re looking at a Lokführer. This literally translates to "locomotive leader" or "locomotive guide."
Interestingly, in many European countries, the role is increasingly becoming "Train Manager" or "Pilot" in very specific high-speed contexts, though these haven't quite caught on in everyday speech.
Does the Name Change with the Engine?
Sometimes.
Back in the day, the person who drove a small, specialized engine in a rail yard (a "switcher" or "shunter") was often just called a Shunter or a Yard Pilot. In the UK, a "Shunter" is both the engine and sometimes the person directing the movement, though "Pilot Driver" is a common term for someone who guides a train over a section of track they are familiar with, even if they aren't the primary driver for that journey.
How to Sound Like a Rail Expert
If you want to sound like you know what you’re talking about next time you’re at a museum or a station, use these tips:
- Context is King: If it’s a big freight train in Texas, say "Engineer."
- The Commuter Rule: If it’s a passenger train in London or Sydney, say "Driver."
- The Subway Rule: If it’s underground and runs on a third rail, "Operator" is your safest bet.
- Avoid "Conductor": Unless they are walking through the aisles taking tickets or standing on the ground with a radio, don't call the person in the cab the conductor. It’s a bit like calling a pilot a flight attendant. They are both vital, but they do very different things.
The Future of the Name
We are moving toward autonomous trains. Rio Tinto already operates massive autonomous freight trains in the Australian outback. When there is no one in the cab, what do we call the person sitting in a control room 500 miles away?
The industry is leaning toward Remote Operator or Systems Monitor.
It lacks the romanticism of "The Engineer," doesn't it? There is something about the image of a person leaning out the window of a cab, hand on the whistle, that "Systems Monitor" just can't replace.
Summary of Actionable Insights
If you’re interested in the rail industry or just want to be accurate, here is what you should take away:
- Use "Locomotive Engineer" for North American heavy rail contexts.
- Use "Train Driver" for the UK, Australia, and most general international conversations.
- Use "Operator" for subways, metros, and light rail systems.
- Recognize the hierarchy: In the U.S., the Conductor is the supervisor, while the Engineer is the technical lead for the engine.
- Check local variations: If you are writing or traveling, a quick look at the local transit authority website will tell you the "official" title used for hiring, which is the most accurate term for that region.
The next time you see a train, remember that the person in the front is managing thousands of tons of momentum. Whether you call them a driver, an engineer, or an operator, they are carrying out one of the most physically demanding and technically complex jobs in the transport world.
Next Steps for You:
If you're fascinated by the world of rail, your next step should be looking into the General Code of Operating Rules (GCOR) if you're in the U.S., or the RSSB Rule Book in the UK. These documents are the "bibles" of railroading and explain exactly how these professionals interact with the tracks and each other. You can also visit a local railway museum; many are staffed by retired engineers who love nothing more than explaining the difference between a "hogger" (an old slang term for a driver who uses too much power) and a "smooth handler."
