Here's the newest member of my B&O roster: GP9 #6463. It's purely a dummy unit at this point although I may add cab figures and headlight(s) later. I had a nice RK GP9 body and the rest of it - chassis, trucks, pilots, couplers, fuel tank are all cobbled together from junk I had laying around. I used a generous amount of dullcoat to give the blue paint that faded look.
This is 98% complete. I will probably do some additional weathering and tweaking before I'm completely done. I used Williams pilots which means they have zero detail so I may upgrade them whenever I stumble across something nicer.
