Campaign trains were a major part of political campaigns years ago. Covering whistle-stopping candidates was considered one of the hardest jobs of journalism. In this edition of Update-1, NPC member Edward Segal talks to Broadcast Podcast team member Irv Chapman about his new book, "Whistle-Stop Politics: Campaign Trains and the Reporters Who Covered Them." Segal discusses what it was like for reporters to live and work on trains for days and weeks at a time, how campaign train tours could be hazardous to one's health, and how one reporter impersonated a whistle-stopping presidential candidate.
