LaidOffSick, Thank you for the note. I would prefer cars that run both directions like my C&O, NYC ESE, and Wabash cars from the first run of the 21" passenger cars.
I don't know why the couplers are pitching upward, but it has caused the coach to uncouple from the train twice. My SP GS4 hit the rear of the train at a good clip and derailed the Observation. The long tongue of the K-matic coupler system is not stiff enough to keep the coupler level. My layout is minimum-72 curves to accommodate my Vison Line Big Boys. The layout has a double S curve along the river that gives the K-matic couplers a workout. On occasion, a car will rock as the K-matic systems swings back and forth and catches.
I guess I would prefer the old trucks and couplers. They worked, although they did spark on occasion.
