Can someone please explain to me how a person who designs and builds bridges and person who opperates a train is the same thing?

@OogieBoogie Right but in all those cases they are actually engineering something. Designing and making something.

@MethDozer engineering is about knowing how something works as a system, it's about understanding how something works and interacts as a whole.

Train drivers need to be able to fix the trains.
(Well, they used to)

So a train driver was essentially a train mechanics engineer.
Traditionally they were the ones that went along and greased the joints , checked everything before the train journey.

@OogieBoogie That would make them a mechanic not an engineer.

@MethDozer Ah but won't a mechanic be like a mechanical engineer? Not sure if it is but it's just a thought.

@AdaXI No. It's two totally different professions and skill sets actually. There is some crossover but also distinct differences.

Sort like how a chemistry and a chemical engineer are two completely different but hmyet similar occupations and skill sets and one doesn't usually make a good other and vice versa.

@MethDozer Well that's fair enough. Like I say I didn't really know but it would of kind of made some sort of sense.
