Woodrow Wilson, in light gray suit, on the platform of the Pioneer Limited passenger train at Chicago Union Station during his 1912 presidential campaign. Trains were used for campaigning as early as 1836 by William Henry Harrison, and first played a major role during the 1896 presidential race between William McKinley and William Jennings Bryan, in which both candidates campaigned extensively from trains. Later candidates used full-fledged campaign trains making "whistle stop" tours across the country. While air travel and television reduced the importance of campaign trains, more recent candidates, such as John Kerry in 2004, have continued to use them. Also see record 1430
