The Odontotos railway was inaugurated in 1896 and was built to connect Diakopto with Kalavrita by rail.
It was one of the most difficult projects for its time due to the particularly difficult terrain
and the high altitude at which it ended, as Odontotos is the most mountainous railway in Greece.
To overcome these difficulties the railway was built with the toothing technique in which the train is hooked,
using suitable gears, to toothed rails on tracks where the ground gradient exceeds 10%.
The railway crosses the Vouraikos Gorge, passing through tunnels and bridges for a long time,
covering a total distance of approximately 22 kilometers.
Today it is mainly used for tourist tours on one of the most beautiful
and impressive routes in Greece and Europe
