Has anyone ever looked into modeling this particular transition period: NYC and PRR merging into PennCentral? How quickly would the locomotives have been repainted into PennCentral lettering? Could you have seen PRR and NYC lettering on locomotives still making the rounds in 1968 or shortly thereafter? Could you have seen a PennCentral painted locomotive in a yard alongside either a PRR or NYC locomotive paintjob? Would the old NYC and PRR painted locomotives be actively used, or more sit in a yard waiting to get painted PennCentral? Another idea - could you have ever possibly seen PRR and NYC paintjob locomotives serving alongside each other after the merger? PRR and PennCentral? NYC and PennCentral?
