DUFF, TEXAS. Duff, eleven miles south of Center in south central Shelby County, was a flag stop on the Gulf, Colorado and Santa Fe Railway and, for a brief period in 1907, the site of a post office. Residents of the area boarded the passenger train at Duff as it passed on its route from Longview to Beaumont. It was also a place where hoboes caught freight trains as they slowed to check for the signal to stop. By 1974 the flag stop had been abandoned.
