Quick Thinking is a 1989 annual story.
Donald is taking a long train of China clay along Edward's Branch Line. All goes well until the trucks push Donald down the hill towards a passing loop ahead. Donald could not stop and to his horror, BoCo is coming up in the opposite direction with some empty trucks. BoCo's quick-thinking driver pushes the throttle and his train speeds into the loop just in time to avoid a head-on collision with Donald.
- Donald's tender is too short in length.
