The NMRA is the National Model Railroad Association, Inc. It is a non-profit educational association whose purpose is both to promote the hobby of model railroading, and to help set standards within the industry. But the NMRA is far more personal than that. The NMRA is people - people across the globe, people in your area, and people just down the street who love model railroading and want to help others get that same enjoyment out of the hobby.
