Yes and no
The first set was a Hafner wind up, that I combined with my brother's Marx Canadian Pacific and played with on the sidewalk in the summer. I have a replacement set, but the original survives only in pictures and my memories.
My first electric train is an American flyer 372 GP-7 with freight cars and an auto unloading car. I still have that, in the box, as well as some duplicates to play with. Santa brought that for Christmas of 1955, four days after I turned 7 years old.
In 1960, I received a Franklin Frontiersman passenger set with figure eight trestle set. Still have that in its original box as well as some duplicates.
