The Silver Vista - D&RGW car 313 - was a narrow gauge observation gondola with a glass roof and open sides (though there were window shades that could be drawn during inclimate weather). The original - which can be seen [here] - was built by the Rio Grande's own Burnham shops in 1947 from outfit car #0313. It lasted a mere six years, destroyed by a fire at the Alamosa, CO, car shops on 30-Sep-1953.
In 2006, the Durango & Silverton recreated the Silver Vista with their own version of the car. This is a page about the recreation. Thanks to Philip H. Walters of Durango for the "under construction" photos.
Here is the frame at Melcher Brothers Steel Fabrication south of Durango at Animas Air park, just a few minutes before the truck and crane arrive to transport Silver Vista to the Durango Yard. These fine folks built the frame and worked out many many tric
