Lionel Paint Swap - Can you see what happened?

The paint on the engine is also lighter that matches the boxcar.

The engine had yellow painted over the blue so it looks darker.

They painted the reproduction Timken box car in postwar Virginian engine yellow and the reproduction Virginian engine in postwar Timken boxcar yellow?

BobbyD, that is exactly right...The yellow paint color selections for this set were actually a perfect match to the originals. But the factory accidentally swapped the items receiving each version of yellow. On previous occasions when Lionel messed up so badly on color, they re-issued shells (like the 2343  conventional classic for example). To fix this problem, they would have had to issue new engine and boxcar shells. Not surprising no effort was made to correct this problem. Nonetheless, the engine looks great with the darker yellow, even if the boxcar looks total weird.
