Railroad Engineer according to Wikipedia

A railroad engineer, locomotive engineer, train operator, train driver or engine driver is a person who operates a railroad locomotive and train. The engineer is in charge of and responsible for the locomotive(s). They are also in charge of mechanical operation of the train, train speed, and all train handling. The engineer shares with the conductor/guard, who is in charge of the train, responsibility for the safe operation of the train and application of the rules and procedures of the railway company.

On many railroads, the career progression is one that starts as an assistant conductor (brakeman), conductor and finally, engineer. In the United States the engineer is required to be certified and re-certified every 2–3 years.[1]

In India, an engine driver starts as a Diesel Assistant or Electrical Assistant (in case of electric locomotives). They then get promoted on a scale: B, A, and A Special. An 'A Special' driver drives the faster, more important trains.[2]

In the United States and Canada railroad engineers are known as locomotive engineers. In the United Kingdom, South Africa, and Australia, , they are known as 'train drivers', 'Engine drivers', 'Locomotive drivers', or 'Locomotive operators'. Among non-American nations, New Zealand may be unique in using the term 'Locomotive engineer' as a designation for a locomotive driver.
