Funny Story
When I started working for the railway in 1989 the department I applied to had never employed a female. As I was going to work trackside you had to have a mediacal. So they got a payroll clark to stand in the corner in the room and wisper my name to check my hearing. She also took a urine sample. Several years later after completeing my appretaship I bumped into her. She told be they didn't know what to do with urine sample so just tipped it away. She said the mens mediacl with just a cough and drop check up. Not sure how that would prove fit to work trackside.
Hope things have improved.
