On this date in 1931, an F3 tornado collided with the Empire Builder passenger train, the pride of the Great Northern Railway. The train had just left Fargo, heading east on a hot afternoon. The engineer and several passengers saw a small funnel cloud to the southwest. The funnel bobbed up and down; then the top of a haystack blew apart. Seconds later, the train shook and the windows blew out in several cars.
