For the California/bay area folks there is a tram from Silver Lake to Lake Agnew over in the Eastern Sierra (near june lake) that has a max of about a 105% grade. Sadly, you can't ride it but you can hike up parts and around the station at the top. Even trying to climb up is quite a challenge. Its quite amazing. Built in 1915 to support construction/operation of the Lake Agnew and Gem Lake dams. I suggest going up in the fall when the aspen are changing color.
