BNSF 645, built in March 1994, still wears its original Santa Fe Superfleet scheme with 24 and a half years of weathering applied. Sometime along the way BNSF initials were patched on, as well as an orange replacement air conditioner and some yellow reflective patches along the sill. Looks like a good candidate for a heritage repaint as it brings up the rear of an eastbound grain train at Eddy, MT.
