https://www.monorails.org/tMspages/Listowel.htmlAn eccentric new railway opened in North Kerry 125 years ago, which was inspired by, of all things, a camel train. Opened to the public on March 1st 1888, this unique railway was the brainchild of a French engineer, Charles Lartigue, who had seen camels in Algeria walking tall and comfortably carrying heavy loads balanced in panniers on their backs. This inspired him to design a new type of railway. Instead of two parallel tracks on the ground, it had a single rail sitting out of harm's way above the sand and held at waist height on A-shaped trestles. Specially-made carriages would sit astride the trestles like panniers.
There was never enough traffic to support the route, and after the line was damaged during the Irish Civil War, the railway was closed in 1924. A short section of track was salvaged, but everything else was scrapped.
However, Kerry people do not give up easily, and a short stretch of approximately 500 meters of the Lartigue Railway opened to the public in Listowel in July of 2003. A new double-side locomotive and two carriages with capacity for 40 passengers were constructed by a railway specialist company in the United Kingdom,
Considering the unavailability of any of the original drawings, this has been a tremendous feat of engineering, and once again people can experience this unique mode of transport.
