Where can I download custom Galaxy railway models?

[Od19]

I've seen some gan made train models that were modeled after trains from the Galaxy railway series. I have found one locomotive modeled after "Big one" that works and one that doesn't work, "Jack the combat train". Where can I find more models like these?

“I’m trying to rebuild the complete Galaxy Railways pack for TS2009 WBE. The original MediaFire link (5dfi3kzlwasb8/Big_One) is still available but incomplete on my end.
If anyone has a Google Drive or MediaFire ZIP with Big One loco, coaches (front & rear), James the Wolf, Jack the Combat Train, and dependencies—can you please share?
