It would help if you could supply a kuid value. That picture could be one of 5 BNSF Dash 9 units, in that specific colour scheme, that are available on the DLS.
How do you know that it has "never been used in trainz"? Have you checked every USA route and session?
I just checked the Web DLS (Download Station link at the top of this page) and those orange-black BNSF Dash 9s have been downloaded a total of 14,379 times.
