As of Summer, 2009 only a handful of Colorado coal trains were still running steel-bodied cars. On the UP, several trains of 1970s-era railroad-owned steel hoppers (UP/DRGW/CHTT/CNW/MP marks) still operate. On the BNSF, the only regular steel-bodied unit coal train is the Rawhide (RAWX) train. The BNSF NPPX train to Gerald Gentleman Station may also still operate steel cars but I haven't seen it in several years.
