Having just received two from JDs Trains last week, I can confirm they do have the typical Lionel 3 rail couplers; unfortunately they don't quite compare to the easy-opening ones Lionel uses on their scale PS-1 boxcars. You will need some powdered graphite to lube the Atlas"O" ones so they are not so tight as produced. These are still "thumb-tack" operated per usual Atlas"O" practice to date.
