Sgauger posted:Only the rear coil coupler on mine works, but it does not open far enough to release the rolling stock. I have tried this with newer Flyer bocxcars, 1950's boxcars, and S-Helper cars. They do not disconnect. Perhaps with a heavier string of cars?

The electrocouplers on my NKP GP7 sample uncouple and couple dependably with the newest version of the L-AF knuckle coupler (e.g., the coupler fitted to the new cylindrical hoppers). My trials utilized a three car consist. However, on various other "Gilbert compatible couplers", your mileage may vary, as Sgauger is indicating. The length of the knuckle fitted on a coupler in question may have an effect (shorter = better). Dave and the guys at the Circle L Ranch were likely using the newest version of the L-AF knuckle coupler in their product development; hence what I am observing.
