I've taken the list of power stations being supplied by the Powder River Basin on Wikipedia https://en.wikipedia.org/wiki/Powder_River_Basin
and cross referenced it with reporting mark lists http://trn.trains.com/railroads/abcs-of-railroading/2006/05/railroad-reporting-marks and https://en.wikipedia.org/wiki/List_of_reporting_marks:_A

While not comprehensive these would definitely be found in PRB as well as BNSF and UP and various leasing companies.

I do not know if any Canadian Pacific or Canadian National Railcars would find their way down here.

Oh, and the UK

Now if you can just tell me where I find 'em at?:hehe:
On a serious note we have access to some those and it's nice to see what's appropriate.
Thanks,

Well, we've got GALX in several flavors from RRMOD/Guido73 and WEPX should be available from sureshot28 on the DLS shortly. That's a start.
