BS user Swoofty has been making some lovely 6wide trains as of lately. His most recent, an EMD E7 unit is a great upgrade of the official version (although the official is an F unit). His use of window panes as steps is my favorite detail. Although nothing particular sticks out in the coach, it's still rather nice.
Be sure to check out his GE ES44DC and SD70ACe as well, the high traction trucks on the former are excelent.
EDIT: I seem to have missed his WIP BNSF Dash-9 loco. It's looking nice so far, I can't wait to see what he comes up with.
