Fifty years ago, Rich Rein, a tall, slender man who is now 71, was the editor of the Daily Princetonian student newspaper. On June 6, 1968, the day after the assassination of Senator Robert F. Kennedy, he received a call from the Kennedy campaign office. Would he like to attend the funeral and ride on the train that would carry Bobby’s body from New York to Washington for burial? The newly widowed Ethel Kennedy had thought that college students should be among the journalists to report on the event. And so Rein ended up on one of the most extraordinary train journeys in history.
