Diakofto–Kalavryta Railway


The Diakofto–Kalavryta Railway is a historic 750 mm gauge rack railway in Greece. Located on the northern Peloponnese, it runs 22 km from Diakopto through the Vouraikos Gorge and the old Mega Spilaion Monastery and up to Kalavryta, stopping en route at Zachlorou.
At the Diakofto terminus the line will connect with the new standard-gauge Piraeus–Patras railway when it is completed; as of 2019 the new track is in place in a cutting through the station yard.
The line was built by the Piraeus, Athens and Peloponnese Railways. the infrastructure and rolling stock are owned and maintained by Hellenic Railways Organisation. Passenger trains are operated by TrainOSE.

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 Diakofto; 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.

Service

OSE recently completed renovation work on the northern part of the line, during which the line was wholly or partly closed., there are three trips on weekdays and five on weekends. Passengers buying a round-trip ticket from Diakopto and taking the first train to Kalavrita are allowed to return later in the day on any of the other trains. An extended service on weekends and public holidays is operated with two additional trains.

Diesel trainsets

The first batch of modern rolling stock for the Diakofto-Kalavryta railway consists of three Diesel-electric trainsets built by Billard in 1958. They were numbered ΑΔΚ 01 to ΑΔΚ 03, later renumbered as ΑΒδφπτ 3001 to ΑΒδφπτ 3003. Three similar trainsets built by Decauville were added in 1967. They were numbered ΑΒδφπτ 3004 to ΑΒδφπτ 3006. These trainsets, both types of similar configuration, consist of two passenger cars and a generator trailer or "OPE" between them. In addition, a steam locomotive is preserved at Kalavryta station and has been used occasionally for special trains.
Four new three-car Diesel-electric trainsets were ordered from Stadler Rail to replace the old rolling stock and entered service in 2009. These are designated as Class 3107.
