I assume it is in this pack: https://jointedrail.com/product/bnsf-cw44-9-pack-h3/
There are three 3 packs of cw449s at jointed rail, this pack has numbers close, but they only show two of the three. And they may use ARN? Dunno.
People reskin JR content all the time, sometimes with permission and sometimes without. It isn't unusual for them to disappear when they don't have permission. I know a couple of users recently that were banned and their uploads deleted after JR complained to N3V.
mrtrain didn't have a site, it was a reskin of his gs-4 released on TCR years ago. it can be found alongside the whistle of "jerry" from blaxland ridge railroad by Dajara521 on a wayback machine archive
No I know that one. In fact, it is installed on my version Trainz. I recently came across a reskin of the Jointed Rail GS-4. Also, what’s the hype of the mrtrain 4449? The JR model is more detailed.
