An Athearn BB SD40-2, I modeled and detailed up to be the BN SD40C. This was the highest HP locomotive on the BN for a while, The C meant it was re-powered with a Caterpillar engine. A lot of DW, DA PSC and other parts on this old loco. Also modified the exhaust to resemble some roof top images I have seen. The model has operating head lights, ditch lights, and step lights.
