I bought a CW-80 transformer for my son for Christmas and tested it the other day. The "Direction" feature doesn't always work even though the direction feature on the locomotive is ON. When I push the direction button, the locomotive slows to a stop but then resumes in the same direction. The pack that came with the set (just the basic Lionel pack without any feature buttons) will reverse the locomotive direction without a problem. I have the pack hooked up properly. Many times, returning the throttle lever to STOP will not activate the reversing circuit. The locomotive is a "Lionel Lines" FA unit that has a horn sound onboard.
