i just got the 4 car set of napa valley from Kline Lionel. both the observation cars have couplers only on one end. it looks like that the coupler on other side could be attached but are just missing. does anyone has that set and can please confirm that couplers only come on one end or its that, mine are missing. if they are only on one side, i do not know how to connect the entire train together with the locomotive
thanks
