Answers by Expert:
I am happy to answer all types of model railroading questions. My specialties are DCC, modeling tips, valuation tips, brass trains, operations, and railroadiana. My emphasis in modeling is western railroading (SP, UP, WP, PE, etc.) but I can help with all areas. I am a lifetime model railroader and a model train business owner. I am NOT an expert on Lionel, Marx, American Flyer, and older tintype trains. I know some values for these but cannot diagnose operational problems via this service. Usually these trains need to be seen in person for servicing. Old plastic HO trains have little value. These are not like Lionel and generally have little value because they are not as well made as modern HO locos.
I have 27 years in the model train and railroading hobby and have a large network of specialty contacts.
