To create a KCS business train,simply purchase Con Cor KCS Smoothside cars which I believe are still available. Then all one has to paint would be open platform business car (cars?) and IM or Kato F Units. Decals I believe exist for locos. Years ago when I did two Con Cor E-8's in KCS to pull my Limited Edition Southern Belle set no N scale decals existed so I used HO adapted somewhat. Later Life Like did this scheme and Con Cor revised better done passenger cars. Nate Goodman (Nato).
