I don't have any history for the majority of the items in my collection, but it really does add to my appreciation for the train when I do. Even when I don't know anything about the original owner, the trains with normal playwear tell that they were loved toys... and the ones that a lot of battle scars tell me that they were played with a lot! I am a bit puzzled by the trains in like-new condition - were they so cherished that they were only brought out on special occasions? Or was the original owner not a train fan, and the toy sat unused and unappreciated for all those years? Hmmm...
I have an early Ives clockwork that came from the son of the original owner, and some other Ives trains that were discovered decades ago in the basement of a hardware store by a person who held on to them for years before selling them to me. A co-worker gave me the remnants of a Marx set that was purchased for him when he was born. The story behind the train can turn even a common item into something special.
I also have my dad's Marx electric train set that was a Christmas present in the early 50's. It was a gift that was made possible because the local REA co-op had just got electricity to the family farm!
For the record, I still have my first train set, or what is left of it. Let's just say I got my money's worth out of it... maybe someday a person will look at it and wonder how it ever got into such bad condition!
