We have a good selection of HO Scale Dome Cars in our Dome Subcategory. We carry leading brand Bachmann with a collection of McKinley Explorer products, and an Amtrak dome can be added to any Amtrak era (1971 and later) passenger train. The HO Dome Car is a model of the dome cars built for the railroads. In 1944 while riding on the Rio Grande Railroad through Colorado's Glenwood Canyon Cyrus Osborn of General Motors (GM built locomotives) had the idea of a "dome" car. The new car was a perfect addition to the streamlined passenger trains introduced by the railroads after World War II. If you have ever ridden in one, you know it is the best way to view the countryside. Take a look at our domes.
