Practicalities: Would being a train driver be plausible in the context of my story? How much would a train driver have earned, eg? Was it a very technically skilled job back then? If not, what other job could he have done on the railway that would need high technical skill, and if such a job existed, would it not have paid too much?
As it is/was a highly unionised organisation, train drivers would have been well paid, probably 30% above the average industrial wage.
