When I was a kid we had a Lionel Train Set, I was told it was a special locomotive, you added some drops of something in the stack & it would puff & chug again & again, So that was pretty cool.
Wish I still had them, I don't even know what did happen to them. Hmmmmm...

I did move onto slot cars, & that was good fun so long ago. My favorite was a Cheetah, with sponge foam slicks.

 

Ok the "smoke" was either an oil or you would crush tablets into the stack. There was a heating element to burn the stuff off. I too had a Lionel set when I was about 8 (?).
I still have a Classic "Stinger" this is blue, not original (1:24)

I was too young, but I do remember my Dad adding some oil from a small bottle in the stack...

Very Cool you still have a Cheetah.

 

Sorry my friend, I have been swamped lately limiting my free time. I will work on getting some cool pictures of some of my stuff as soon as I can.

 

 

yea, I was into the slot car thing for awhile too. chaparral

 

Wow !!! You got pretty serious. I never took it that far. by that time I was working on removing the govenor on my Go-kart. And yes I did blow up the Briggs engine, my Dad was less than thrilled.

 

I have the Stinger not the Cheetah.

 

Yeah I had one also, too.

 

Doh !! my bad.
