I don't know. It was 1958 and all I wanted for Christmas was a Lionel train set in the Sears catalog. Instead, I got a huge collection of used AF passenger and freight cars with a K4 Pacific engine. Loved it. Now I buy MTH Premier and Lionel Legacy. MTH brought me back to O gauge. My first purchase was the MTH NYC Hudson in 1997.
It has to be scale proportioned for me.
