In my experience, Amtrak has the most remarkable Lost and Found Department. On one of my trips Inadvertently left my little medicine bag in my Roomette on the Capitol Limited arriving into Washington DC, and I had no idea that I had done that. All that I discovered upon return at home is the bag missing. Since it was the last leg of the trip there was hardly any medicine left in it, so I thought it would be a waste of time to try to chase it down.
But lo and behold, I got a call from Washington DC Lost and Found in a few days regarding this item. They had opened the bag figured out who it belonged to, figured out that I am an AGR member, pulled my telephone number (having a very unique uncommon name helps I suppose) and called me and asked me how I would like to pick it up. I requested them to ship it to new york, which they did via 66 that night, and I picked it up at New York Penn Station baggage claim the next day! I was absolutely amazed!
