I recently picked up a Lionel UP GP7 and matching caboose. I think these were made in 2010. The GP7 had a small problem with a sticky motor truck that I had to modify so it would not derail on O-31 curves. The truck frames were sticking to the cab mounting screws underneath. The screws can not recessed due to a small protrusion on the motor frame. The side frames of the truck would get caught on the screws when the loco came out of a tight turn. Anyway, I filed down the truck side frame and all is well.
The gray color on these pieces is quite light in comparison to most others. I thought it was a pleasing color combination.
