We hear about classic car "barn finds" often nowadays. How about a 60 foot heavyweight RPO-Baggage-Coach?
In the Eastern time zone we're presently watching an episode of Restoration Road called "Idaho Train Car", It's an episode of a series on Magnolia Network (formerly DIY), involving the refurbishment of Washington, Idaho, and Montana No. 306, built by ACF in St. Louis in 1909, and recently found in a barn in Idaho.
It's missing its trucks, and is in dreadful condition, but will be apparently turned into a tiny house with a covered station platform as its front porch and wrap-around deck.
Many, but not all, interior features are being, rebuilt, restored or recreated.
If you're west of us you might be able to catch the whole episode. I'm sure that it'll be rebroadcast in the future as well.
