The Other Two Trains
Along the Pennsylvania turnpike there is a mountain with two tunnels under it. One is a large two-lane tunnel for cars and trucks. The other is a small tunnel for one train to go through. One day two trains entered the tunnel at exactly 8:00. They both traveled in opposite directions. They both passed the middle at 8:01, but they did not crash. Why not?
Answer
The "trains" were not locomotives. They were two long lines of cars traveling in opposite directions through the two-lane tunnel. Any long line of vehicles, people, etc. is also known as a train.Hide Answer Show Answer
