Model Railroads/Expert Profile

Ask A Question


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.

Experience in the area

I have 27 years in the model train and railroading hobby and have a large network of specialty contacts.

Hi and thanks for your question.    PSC bought out the PFM brass lost wax castings and can manufacture odd items for a cost if they have the master.  I would suggest you get the dimensions and a picture

Hi and thanks for your question.    There is no plug and play decoder for IHC/Mehano locos. You will have to partially dissemble the loco, isolate the motor per the instructions, and install a standard

2012-11-26 Trains Direction Movements.:

Each track should have a primary route flow of traffic.  Especially with 4 mainline tracks.  When necessary, a train can operate against the normal flow of traffic with proper orders from the dispatcher
