Local 6ABC News reports that this guy was with Amtrak for 9 years, an engineer since December 2010 and a conductor before that. At age 32, that would make him 23 when he started.
By your definition of "conductor," how does a 23 year old become "the senior employee on the train and is in charge of it?"

Doesn’t say he was a conductor at 23, just that he was a conductor prior to becoming an engineer.
We all started somewhere. I started learning how to design railroad signal systems at the age of 20.
