Indeed, but GE and EMD don't have to ship their engines to China to be painted and get them back here. My understanding is that some of the striping is wrong but I'm not a big enough NS fan have even noticed. I suspect this means a complete redesign of the paint job, manufacturing and painting new shells in China, slapping them on the returned frames, and getting them back here. I imagine they will just bin the incorrectly painted shells rather than stripping and repainting them. All this has to be worked into slack periods of their regular production schedule. If I had to bet, I'd bet that four months is optimistic.
