Expertise:  I CAN NOT DIAGNOSE equipment problems or ESTIMATE DOLLAR VALUES of your equipment, by email. I have been active in model railroading for forty years. I can answer, or find answers, to questions on most aspects of model trains, railroad equipment or buildings. I have a good knowledge of prototype railroads. I have been employed by five model railroad equipment manufacturers/suppliers and worked for a prototype railroad. I have served, twice, as the president of a local model railroad club. I have been employed as a Reference Librarian, at a university, for the last fifteen years and am used to tracking down resources for patrons.
