BOB2,
Welcome to our topic. 
Glad you stumbled upon us. I used to worry about which categories to post topics under and then I found this blurb from a TCA article entitled "Scale or Tinplate," by Joseph Lechner:
The tubular track used for O gauge, S gauge and standard gauge trains is still made of tinplate today. Postwar trains that run on those tracks are called tinplate too, although nearly all of them are made of die-cast metal and plastic.
So, I run my (prewar) locomotives on tinplate track, so it seemed fair to post this under tinplate, but that just me.
If you like that sort of thing...categorizing, terms and origins of terms, you might like an article I wrote in the Tinplate Times about the term "Semi-scale."

In writing the article, I had contacted Bruce Greenberg and also Joseph Lechner to see if they knew of the origin of the term "Semi-scale." Both were kind enough to respond and said they were not aware.
I like your locomotives. I have one of the 1989 re-releases and I once met Myron and still have the OGR screwdrivers he gave me.
Glad you like the old versions better than the new ones, too.
Tom
