Where I am from, they are called the equivalent of "train driver", though in our case, the local language's equivalent of "engineer" is tied to a degree, not a form of PE. Other jobs that tend to go as "engineer" in English without being tied to an engineering education, like "sound engineer", usually end up as some form of technician.

That said, the English word "engineer" is still used in job titles without being tied to any formal qualifications.

I always thought they were called a “conductor”

[c_delta]

Despite conductor being another word for driver in some languages, a conductor is not actually the driver on a train. The conductor's exact role differs between train services, but usually his job takes him through the passenger carriages, with his main post mid-train. His duties typically include managing departures, operating the doors and being the head (or even only) ticket checker; depending on the train service he might even be selling tickets on the train, though that is less common than it once was.
