I have a 1960’s vintage HO set. Not sure the exact year. I am looking for a bulb replacement for the Sante Fe engine. Lighted F9 “A” diesel. The train runs on 18 volts. I would also contemplate an LED replacement. Any help with part numbers would be great. And if anyone has a parts breakdown of the engine. The engine runs great but I know eventually the brushes will wear. I haven’t set up the trains in over 40 years. They have been in storage.
