Suddenly, one engine is out of order. The train driver, Thomas, thought it is not a big deal so he just turned off the engine and use the other engine to keep the train going.
After a while, the second engine broke down, too.
Passengers asked Thomas, "What happened?"
Thomas said, "I have good news and bad news for you. The bad news is both engine just failed and we will be delay for at least few hours."
A passenger asked, "What is the good news?"
Thomas said, "The good news for you is that you choose to take the train, not an airplane"
