The thread in the WIP forum got a bit long, so I thought I should start a new thread now that I (finally!) released the car.
It's freeware and you can download it here: http://golden-age-rails.com/freightcarpacks/prrk7a.html
Repaints are very welcome, I don't plan on doing more versions of this car. If anybody wants to get the layered texture source file for this model, please send me an email -- also if you may need some rearranged autonumbers in the process.

Cheers,
Michael
