Welcome to the club, CN! GP40-3 #7600 and slug GY-430A #600 have been repainted into Canadian National's classic green and yellow paint scheme! Although the shade of green is lighter than the original livery, they still look great as these are Canadian National's first official heritage units! Also, I believe this makes #600 is the first heritage slug.
