From Rick: "I guess they need to update their parts website; it can still be purchased online."
Thanks, Rick and all of you. I went back online to the site you gave me, and I did manage to place an order for that transformer. I also called Lionel and kindly brought this to their attention. I can't believe that I keep running into this type of incompetence at every turn now, whether it is the doctor's office, VA, insurance, you name it, it seems I never can get someone to help you with clarity. Thanks again to all of you for your help. Jim
