hello to all:I have a tanker that has no couplers on it what I did was to change the bogeys to 45681:50001. the original trucks came with bogeys but they look fake so I changed them how do I get those bogeys back I put in  in the config file bogey-2  and kuid:76096:50002> but the tanker says tag bogey-2 and tag bogey-3 not permitted within this train car.so I had to delete both of them.  so how do I get these couplers back? is it in the script? any ideas? brakemen
