Typically, you have to whack the cars pretty hard to get a coupler to close, again dependent on the coupler. As far as releasing, sometimes they won't release with a load.
Another issue is track voltage, many times you'll find couplers won't function well unless you have at least 16-17 volts on the track.
I was going to start a new Post, but did a search and found the above Reply on a prior posted topic that already covers this issue.
I have LC+ New Haven FAs with electrocouplers. At 16 volts, the electrocouplers made the sound of firing open, but did not open. However, at 18 volts they did both.
Raising the voltage to see if the couplers would work was a passing thought. I was very happy to see that this turned out to be the solution. Arnold
