I remember REA, including their trucks and the depot they had at the east end of the Penny's Sunnyside yard. I also remember that when we went on vacation by train in the 40s, my mother packed a large trunk that was picked up the day before we left home and delivered to our hotel 2-3 days after we arrived. There was a similar delay on the return to home. I don't know where the delivery delay occurred but is always struck me as less than "express" service.
