under the control of OSE. In 2019 services were suspended due to a landslide. Extensions Tripoli: The original plans of the line envisaged the extension of the line from Kalavrita to Tripoli, but it was cancelled for financial reasons during the construction phase of the line before any works had begin. Agia Lavra - Chelmos Ski Station: Since 1996 OSE. has been planning an extension of the line from Kalavrita to the historic Monastery of Agia Lavra and the Ski Center of Kalavrita with a length of . In January 2021, the issue of extension entered the auction trajectory due to the celebration of the National Uprising bicentennial. In the first phase, there will be a bus connection of the cogwheel railway from Kalavrita to Chelmos Ski Station. Technical information The railway is single line with gauge. It climbs from sea level to in with a maximum gradient of 17.5%. There are three sections with Abt system rack for a total of 3.8 km. Maximum speed is 40 km/h for adhesion sections and 12 km/h for rack sections. There are many bridges over the Vouraikos River, numerous tunnels, and passing loops at Niamata, Triklia, Zachlorou and Kerpini. The rolling stock sheds and maintenance facilities are located at Diakopto; there were additional facilities at Kalavrita station during the steam era, but they are no longer in use. The line was to be electrified and electric multiple units were ordered from Billard in France. Before the cars arrived, the electrification plans were cancelled and the electric multiple units were thus not usable when they arrived. As a makeshift solution, a power car carrying a diesel generator was placed between the two cars, a solution that has worked very well for decades.
