A large two engine train was crossing America. After they had gone some distance
one of the engines broke down.
“No problem,” the engineer thought, and carried on at half-power.
Further on down the line, the other engine broke down, and the train came to a
standstill. The engineer decided he should inform the passengers about why the train
had stopped, and made the following announcement:
“Ladies and gentlemen, I have some good news and some bad news. The bad news is
that both engines have failed, and we have no power. The good news is that this is a
train and not a plane.”
