Well, yes and no.
It is a GE product, but it was rebuilt at the shops down in Mexico, right? (Empalme, if I'm not mistaken, yes?) A "home-grown" project using GE products and support?
I'm going to allow it, as a railroad's own rebuilding program kinda falls under the "rebuilders" category of this forum (hey, my discretion, innit?). Unless evidence proves otherwise (I'll leave that to the prosecution and the defense. Hey, I was a Criminal Justice major for 2.5 - 3 years of my college career, have to put it to use somehow!).
Now, given it has the "S7R" designation, I'm assuming that's a "Super Seven" Rebuild, yes? Or am I incorrect on that line of thinking?
