Alpine Coasters are quite famous now and you may find many of them in mountain resorts where they are used as summer sled attractions.
They are built by Wiegand, a German company, they are small roller coasters where individual sleds are pulled up to the top of the track with an automatic cable car system. Then the sled is dropped in a steep slope with many curves.
Near Da Lat (Vietnam), there is a very interesting Alpine Coaster.
There, the Alpine Coaster is used both as a thrill attraction and also as a real transportation system. The Alpine Coaster is used to reach and visit Datanla Falls which at the bottom of a gorge. As the contrary of the other coasters, the departure is located at the top of the track and the sleds have first to go down on the slope to reach the bottom of tha track at Datanla Falls. There you leave the sled to visit the falls and after your visit you take another sled which takes you back uo to the top with the cable car system which is a real funicular.
The Mauch Chunk, Summit Hill & Switchback Railroad commenced operations on 1827 for hauling anthracite from mines at Summit Hill down to the Lehigh River at Mauch Chunk.
It took one half-hour to roll downhill the loaded carriages. Empty carriages were hauled by mules to the Summit Hill during a four hours trip. Mules returned downhill in a special car with the loaded carriages.
In 1846, the mules were replaced by two steam powered inclined planes, Mount Pisgah and Mount Jefferson, but still with the gravity system.
In 1872, new roads were built and the gravity railroad was not necessary anymore… but the Switchback Gravity Railroad was bought and developped as the first roller coaster tourist attraction!
The Switchback Gravity Railroad countinued operations until 1932… after more of 100 years of operation!
For me it’s still is the most interesting railroad ever built, it comprised deux steam powered inclined planes, with two systems to push wagons, and two gravity railroads… !
Yes, the solution of Quiz #21 is the roller coaster “Orphan Rocker” in Katoomba, Australia.
Orphan Rocker (D on Google Map)
This roller coaster was built in 1982 by Harry and Philip Hammon, original owners of the Scenic World of Katoomba. This roller coaster was never been opened to the public! The project started as a monorail ride but soon evolved into the first Australian designed and built roller-coaster. It was named after a nearby rock formation, Orphan Rock.
The “Scenic World” has 3 attractions: the Scenic Railway, the Scenic Skyway and the Scenic Cableway.
The Scenic Railway is a funicular (415m length, 206m of difference of levels) which has a 52° angle slope which corresponds to 128% maximum gradient (the steepest incline in the world)!
