PRR K4s Wood Model Plans/Dwgs

I appreciate woodworking as well as railroading. I am looking to locate scaled drawings, plans, or patterns suitable for building a model PRR K4s Pacific and/or a standard P70 coach out of hardwood. I have access to all the woodworking equipment. Do any of you have suggestions as to where I can find the plans or a supplier of QUALITY working wood railroad model plans? I envision driving wheels that rotate and tender trucks that swivel. The effort I would put into building a model like this would compare to what I put into building a piece of fine furniture.
