There have been many reports about how suburbanites (back in the 1920s or -30s) could phone a grocery order in to a merchant or merchants at Reading Terminal Market and have the package transported later that day in a working baggage car (which some suburban trains had back then), and meet the train at Ambler or somewhere and claim the package from the baggageman, being billed monthly by the merchant, but I've never seen any mention of the transportation itself. Does anyone know whether there was an actual published tariff covering this service, or was it completely informal, and provided as a courtesy? Back in that era, a railroad could not legally provide any service for anyone unless it was published in detail in a tariff on file with the Interstate Commerce Commission and any relevant state regulatory agency. Tariffs hardly ever got saved (would anybody bid on an old freight tariff at an auction?), but if there was such a thing it would be a real find today if it survived.
