My adventure in 3 rail was different than most.
My first actual electric train was a simple little Marx HO set received for Christmas in 1958. (I think). It did not survive the rambunctious ways of this 6 year old: By summer of '59 it was played to death.
It wasn't until about late 1959 or sometime in 1960 that friends of the family gave me their son's train set he had outgrown. (He was heading off to college as I recall?)
It was a little Marx 999 litho set w/8 wheel cars.
I couldn't play that set to death! I had a lot of fun with that little set. That little Marx train ran for hours upon hours and smashed through whatever was placed in front of it with nary a dent!
My little Marx set was the closest I came to owning "Lionel".
Ironically, Lionel was what I was wanting for my train set of 1958, but neither me, or for sure my parents, knew what they were doing with model trains so I ended up with an HO Marx set! Well... to my young eyes the engine in the Sears catalog picture LOOKED like those "Santa Fe" Lionel engines! (Hey, I was just learning to read!) SO, mom and dad ordered the train set I indicated... only to learn upon opening it that it was an "HO" train. Surprise!
For Christmas of 1962, I received another new train set: An HO scale Lindberg Lines set. THAT Lindberg Lines Christmas gift set the hook in me for HO, and it wasn't until 1990s and I was in my 40s that I had any desire to revisit 3 rail. (Which I did with a vengeance!)
Here's a nigh-exact replica of my little Marx set that I purchased some years ago for Christmas Tree use:
The boxed set...


And here it is serving Christmas duty...

And here's a replica set that I have to replace my Lindberg Lines 1962 Christmas set...


Sadly, only ONE piece of rolling stock from my original Lindberg Lines set has survived the 64 years since receiving my original set. (Three cars had survived up until a move, when two disappeared!)
Anyway, here's my surviving Lindberg Lines boxcar that has survived all these decades...

The above Lindberg Lines C&NW boxcar has seen service on ALL of my HO layouts that I've built since 1962! (Five layouts.) It is seen in the above pic in service on my current HO layout.
Model trains have essentially been a life long interest that eventually led to earning a railroad retirement!
