Happy New Year. Here are two more hoppers for the layout, nothing special, simply two Bowser hoppers out of the box with the addition of added cut levers. However, I'm wondering why there is a colored section near the bottom of the corner post on the UMP hopper. I first noticed this in an Everett Young photo of these cars in Shelby, KY. I've seen several Chessie hoppers that have this same marking albeit in blue. Please make a comment if you know what this is for. Thanks.
