If it is the K-Line Collector's Club be sure that the side frames on the trucks are attached, some of the K-Line collector club GG-1's will lose the sides on the trucks because of zinc pest, mainly a cosmetic thing. Also the collector's club when it says TMCC ready just has a plug-in for TMCC and nothing else.
If the K-Line GG-1 is full scale then it should not have any issues that I know of.
