I am from the Scranton Area, which is very close to the Poconos. I would suggest possible seeing if Walters Hardware in Wilkes-Barre maybe able to fix it. They seem to have a good service and are very nice. One mentioned the Pittston Train Shop, which is not a bad idea either. I am not sure if Walters or Pittston Train Shop are authorized lionel repair techs or not.
