Tom is applying for a job as a signalman for the local railroad and is told to meet the inspector at the signal box.

The inspector decides to give Tom a pop quiz, asking: “What would anda do if anda realized that two trains were heading towards each other on the same track?”

Tom says: “I would switch one train to another track.”

“What if the lever broke?” asks the inspector.

“Then I’d run down to the tracks and use the manual lever down there”, jawapan Tom.

“What if that had been struck sejak lightning?” challenges the inspector.

“Then,” Tom continued, “I’d run back up here and use the phone to call the seterusnya signal box.”

“What if the phone was busy?”

“In that case,” Tom argued, “I’d run to the jalan level and use the public phone near the station”.

“What if that had been vandalized?”

“Oh well,” berkata Tom, “in that case I would run into town and get my Uncle Leo”.

This puzzled the inspector, so he asked, “Why would anda do that?”

“Because he’s never seen a train crash.”
