I always liked the Sloan yellow color the Katy painted their cabooses and boxcars. The Accurail lettering is pretty accurate so all I did was replace the ladders with those I made and wire hand grabs. Weathered with pin washes are out d the rivets and door details using black and brown. I ordered a bottle of Vallejo Brown Wash after seeing an O gauge SLRX car using the wash over the white sides.
