How much money does a railroad freight conductor earn?

Starting pay for conductor trainee at Canadian Pacific is 3 months at $731. per wk with overtime pay after 40 hours at $27/hr. After training and once your pass your exams and are marked up to Conductor you start receiving 85% of the paygrade for a Conductor. That is about $4,200 mo. without any overtime. That is a guaranteed amount, however most guys always make more than that. The HR manager told me 1st year earnings that could be expected are $38,000-$54,000. Once trained as an engineer average pay is $75,000 and going up as high as $125,000 depending on overtime, extra boards, etc.
