Blue/yellow is my favorite. My first ever HO engine was a Tyco F unit painted in the blue/yellow freight scheme. That sealed the deal for me, even with its broken rear coupler. I have a fantasy MTH Dash-8 40CW painted in blue/yellow and I dig it. I also really like the 9647 paint scheme (have a MTH PS-1). Silver/red is nice, just can't get behind the current BNSF scheme. I tried to like it, looks ok on the SD70ACe, might just be cuz I like that locomotive...
Laidoffsick, I like your SF wall, very nice.
