The National Train Show® was established in 1988 by the National Model Railroad Association as a nationally sponsored combined industry trade show and public train show to promote the hobby of model railroading. The 2019 National Train Show is held in conjunction with the national convention of the NMRA in Salt Lake City, UT. It will be held in the Mountain America Exposition Center (formerly known as Southtowne Expo Center) in Sandy, UT.
