I'm trying to figure out what that car did when it was on the steep part of the track to keep people from leaning forward at least 30 degrees. https://maps.app.goo.gl/K6MJ9d488wVcJYvR8
Dennis DeBruler : A photo, https://goldenhistory.pastperfectonline.com/photo/20138D44-3241-4C1B-87D6-375292593320, shows that the seats lean backwards. So the people in the postcard must not be setting with their backs against the seat on the more level part.

The snow highlights the former right-of-way.

"For many years this peak had a dance hall.  Curiously, this dance hall was used by the KKK for a period of time in the 1920s."
[The dance hall was built in 1908 and the funicular was built so that it was easier to get to the hall.]

There was also a Funicular up Lookout Mountain.
