It looks like a rack railway that uses a cogwheel in the engine to make it up and down the steep grades. There's no way friction between the wheels and tracks would keep traction. I've seen them on TV a couple times and wanted to ride one ever since. Many years ago I decided to see some of the sights here in Michigan. I bought a DeLorme Atlas & Gazetteer which to the best of my memory has 106 map pages that are so detailed it shows the driveway on my uncles' farm. Actually I think there are more pages of maps, about 133 of them but page 106 was the one with the farm on it. It's a 1/4 mile lane and shows up as well as a city street or highway. It has several pages listing the names and alpha-numeric grid locations and pages of many, many campgrounds, unusual natural features and the usual, lists 123 waterfalls and their locations and tells you there are 12,000 lakes and 30,000 miles IIRC of streams and rivers. It lists a LOT of stuff and tells you where a bunch of tourist destinations are, all the state historic sites and national historic sites in the state and way too much other stuff to remember. I haven't actually looked at it in years but I always take it with me when I go up north just in case I want to go see something. Being paper you can take it anywhere (except in the water), doesn't lose every file like my computer did this month, and it never needs batteries. Mine has routes I highlighted and a few brief notes from places I've been.

Perfect for sightseeing, exploring back roads, outdoor recreation and trip planning If anyone is interested in the DeLorme Atlas & Gazetteers I can look at mine and post what things are actually listed by section, like every city and town, lakes, campgrounds, etc. You can look at your local sporting goods store and probably see with your own eyes. Lots of stores used to sell them, but I don't know if they still do sell paper atlases in the digital age.
DeLorme built the the world's largest rotating and revolving globe, named Eartha. Eartha has a diameter of over 41 feet and weighs approximately 5,600 pounds. It took 2 years to build it. It's mounted at a 23.5 degree angle, the same axial tilt as the Earth, and simulates one day's revolution and rotation every 18 minutes. Garmin bought Delorme in 2016 and Eartha is still there in the former DeLorme corporation headquarters in Yarmouth, Maine. That's something I want to see some day but it's a long way to go to look at a globe.
