When I worked for the Boston & Maine (1968-86), the former Supervisor of Mail Traffic, E. A. Lindberg, now deceased, was somewhat of a railfan, and he recounted interesting happenings in the railroad world. Railway Express was one of them. Outside major cities, Railway Express usually occupied space in a railroad passenger station and it was billed for rent, utilities, etc. In many small towns, there was not enough business to justify an employee, so the local railroad station agent was paid a commission on express shipments originating from the station. Mr. Lindberg told the story of a furniture company on B & M's Conway (NH) branch whose products were profiled in Better Homes and Gardens magazine in a post-World War II issue. The furniture was a hit and it set off a home decorating trend that lasted for several years, years in which the agent earned more per year in Railway Express commissions than his railroad earnings. He probably did most of his REA paperwork on company time too. I think the station was Mount Whittier.
