I have an MTH (Lionel Corporation) O gauge No. 249E Christmas passenger set. There is some problem with the tether, I think. I had to send the locomotive and tender back to the original hobby shop twice to get it repaired a few years ago when it was new. It came back working after the second repair but with a huge tie-wrap around the cable leading to the tether bar in the locomotive. The set was packed away for a couple years. I decided to put it under the tree this year. Here it is actually working fine a hour ago. This unit has "special" Christmas announcements instead of yard chatter. Have to admit, the Christmas announcements are a little weird. I videoed the last run before the problem. At the end of the attached video, I shut down the locomotive with the SU/SD button on the remote. THEN... THEN, the tether? problem reoccurred. Symptoms are: 1) Locomotive still responds to speed and direction controls, 2) Locomotive headlight is off, 3) There are no chuff or other sounds from the tender.
I've got to conclude that this is fundamental design issue with he 249E. I'm assuming the tether comes loose in the locomotive somehow. I'm not brave enough to dismantle the locomotive to try to find a fix. I'd be happy to replace the funky bar tether connection with a wired version if that would solve the problem. Can Henning's undertake such a repair? I hope so.
Thanks for your time.
