Odontotos used until now six rail cars like the one on the picture designed and constructed especially for the Greek rack railway and adjusted to the environment of the network (this involves the curves of the line, the height of the tunnels, the resistance of the bridges and the rails).
The trains are made in France: the first three train (delivered in 1957) are “BILLARD” and the other three (delivered in 1967) are “DECAUVILLE”.
It is almost unknown to everyone how the rail cars are electric powered.The necessary electric power is produced at the moment in generating sets located in the middle vehicle, but if the line was electrically powered this vehicle wouldn't be necessary.
The (N1) vehicle which is always directed towards Diakopto has 4 axes and a tare of 11 tones. It is called the driving vehicle because it has the electric motor and the driving wheels (toothed and simple).
The (N2) vehicle produces energy that's why it is called vehicle of energy production (OPE). The motor on the Billard make has the force of 350 horses at 1500 revolutions per minute whereas in Decauville make has 500 horses at 1500 revolutions per minute. OPE's electricity is fed to the driving vehicle while it is going up to Kalavrita and it follows by pushing. OPE weighs 7 tones.
The (N3) vehicle is always directed towards Kalavrita and it is called the governing vehicle because of its control system. It weighs 7 tones and has 4 axes. It has a toothed wheel but it is only used for braking.The trains always travel with the driving vehicle downhill and have three control systems for driving: one at each side of the driving vehicle and one at the governing vehicle. Seated passengers are 81 both in 1st and 2nd class and in total the rail car can carry 100 people.
There is also an efficient porter. The speed in conventional lining reaches 40km/h and in the toothed lining 12km/h. The maximum inclination in some parts reaches 17.5%.
On 19 May 2003, they started renovating the line of Odontotos Diakopto-Kalavrita which is expected to finish within 2009. The cost of the project amounts 37million Euro.
The renewal of the existing infrastructure involves the construction of new superstructure (new train new tracks, new sleepers and macadam).
At the same time there is an extensive maintenance of metallic bridges.Moreover,the procurement of four new trains has already been made (from the Swiss company STADLER). These trains will replace the existing ones which are in use for more than forty years.
