These are Bachman Spectrum F40PHs from 1990. I ran them once then removed the details and stripped the paint as the factory finish was crappy. I unpacked them 03/10, removed the factory plow pilot, fabricated a new pilot and added a DA snow plow. Also filled the oversized grab iron holes and drilled new ones adding scale grab irons and MU hoses.
I added black pigment to the roof from the exhaust rearward but kept the loco fairly clean. They still run smoothly. I have to reconfigure the coupler mounting as they project too far out from the body.
