WORD ORIGIN

When rail travel was still common in the U.S., trains didn’t make regular stops in many small towns. If there was freight or passengers to be taken on, the rail station raised a flag or some other signal to let the engineer know to stop. If passengers wished to disembark, they would tell the conductor, who in turn signalled the engineer by pulling on a cord. The engineer acknowledged this by blowing the whistle. This gave birth to the expression "whistle-stop town."

Former U.S. President Harry S. Truman invented the "WHISTLE-STOP TOUR" during his famous 1948 election campaign tour. Truman and his entourage travelled 30,000 miles by train, stopping at more than 200 towns. Truman stood at the back of the train, giving short speeches at each stop. The strategy was to reach out to as many voters as possible, particularly in small towns where he wanted to polish his image as an "average Joe". The strategy worked, with Truman pulling off what is considered the greatest election upset in U.S. history by defeating the favoured Republican candidate Thomas Dewey.

The expression has meanwhile been expanded to refer to any journey that involves brief visits in lots of towns or cities. WHISTLE-STOP TOUR is also used in a figurative sense when to describe conveying information segmented into a series of concise overviews on different topics.
