The rack railway which links Kalavrita with Diakopto going through Vouraikos Canyon, is one of the most beautiful natural sights in Greece. It has been mentiοned as the most beautiful train trip in Balkans. Diakopto is located 22 Km near Kalavrita.
The journey takes one hour and the speed of the train ranges between 30 and 40 Km/h at usual rail and 6 - 15 Km/h at cogs. The slope of the ground does not allow the movement of a usual train, so between the rails there are cogs that allow the operation of a mechanism to raise the train from the level of the sea at the station of Kalavrita which is 750 meters above the sea level.
The little cog train known in the past as the 'odontotos' (= tooth train), is well known to train lovers all over the world, because its journey along the gorge, is one of the most spectacular railway rides. It consists of two Decauville passenger wagons with the small diesel unit engine in between.
The narrow gauge tracks follow the stream bed of the Vouriakos river and the little train travels through streams climbing the fantastic narrow gorge up into the mountains, through tunnels, over waterfalls, along cliffs and through forests of pine and oleander. When the incline gets really steep it switches from regular track to a cog system.
Occassionally you meet people hiking down the gorge and the train has to slow down to a crawl while the pedestrians hug on the walls of the cliffs. Zachlorou is the train stop before Kalavryta where many people get off the train to hike downwards the gorge.
Next to Railway there is a path, which is a part of international path E4. This is used by a lot of hikers. Places like the Vouraikos gorge deserves your visit as well as your protection since this sort of natural beauty is rarely found anywhere in the world.
