This video was made by Kobalt Tools company (Lowes), and their tools are clearly visible being used by the restoration crew, but this
not a "commercial" by any means, IMO.
Its just a great video about a difficult restoration.

More on #168:
https://en.wikipedia.org/wiki/Rio_Grande_168The passenger cars were not "handed down" from the Rio Grande Railroad, these were more or less recovered & rebuilt from 'non-railroad uses' such as farm sheds etc.
