But machines aren't driven. And engineers build them. Are people who drive trains really engineers? :O

When I didn't put "train engineers" it considered wrong. Now that I put "train engineers" it considered wrong again. Three times that I changed my answers and still get wrong.
Poor translation of masinis ... What not use machinist
