A brilliant young teenager was undergoing track safety training with the railway company.
The interviewer asked him: “Do you know how to use the equipment?”
“Yes”, the boy replied.
“Then what would you do if you realised that 2 trains, one from this station, and one from the next were going to crash because they were on the same track?”, the interviewer asked.
The young applicant thought and replied “I’d press the button to change the points without hesitation.”
The interviewer continued, “What if the button was frozen and wouldn’t work?”
The boy cleverly responded with, “I’d run outside and pull the lever to change the points manually”
“And if the lever was broken?”, the interviewer asked.
“I’d get on the phone to the next station and tell them to change the points,” the boy replied.
“And if the phone was broken and needed an electrician to fix it?”, the interviewer asked him.
The boy thought about that one for a minute, then replied “I’d run into town and get my uncle”
Puzzled, the interviewer asked him, “Is your uncle an electrician?”
“No, but he’s never seen a train crash before…”
