Question regarding scale - Can I change from H.O. to a different one?

Before I ask my question, I have to say that after a long enough break partially by choice and partially not by choice from Trainz, I came back from the perfect time to see 2019 out and of course, the first thing I thought was "SHUT UP AND TAKE MY MONEY!" and I am SOOOOOO GLAD I did! To the devs, you guys really hit it big!!! I absolutely LOVE IT!! Now, my question, When I started my route I chose without giving it much thought HO gauge I believe. After using some of the new turf FX textures on the smallest scale, I'm realizing that the scale I chose is ummmm....tiny vs. the texture scale. I can attach screen shots, but I figured I'd ask first and then if needed, add a screen shot of textures against trains. Grass looks fine, but asphalt with cracks (its a PBR and I cant remember more than that off the top of my head).
Thanks in advanced!

Disregard as problem has successfully been identified as P.E.B.C.A.K.

Scale only affects the Trainz ruler scale of measurement ... trains and track are always the same size

OP was referring to the scale of textures, which can be altered by the user during application in Surveyor edit mode using the scale and radius tools/ dials.
Seems he rediscovered the controls in the meantime! Lovely to see the tech support P.E.B.C.A.K acronym revived. (Problem Exists Between Chair And Keyboard)
