Does anyone know who BPEX is? BPEX 2101 - RailImages.com I can't seem to find anything that goes by that reporting mark.
I have not found anything on BPEX, but there is a BREX (Big Rivers Electric Corp.) Maybe part of the paint wore off. Also as a side note, marks ending in X are not a common carrier, which means they are not licensed to operate for hire, so that would fit BREX.
