SAFETY SYSTEMS: The safety systems of the Metro are among the most modern ones in Europe and have been designed and implemented on the basis of the fail-safe principle, so that any failure will lead the system into safe mode for the passenger.

All trains are equipped with automatic protection system (ATP). This system will immediately stop the train if the authorised speed is exceeded by the train driver or if the next track circuit is occupied by another train.

All signaling and surveillance systems are supported by backup systems of immediate operation, so that, in the event of failure of the active system, the backup system shall be operate immediately. All systems are supported by uninterrupted power supplies so that the system will continue to operate for a sufficient period of time even in case of failure or breakdown of the power system. 

The automatic train monitoring system (ATS) is running in the Operation Control Centres of Lines 1, 2 and 3, through which traffic controllers are aware at all times of the position of the trains, can plot routes and control their movement.

Lines 1, 2 and 3 are certified with the highest safety level SIL 4 (Safety Integrity Level).

In addition, the Operation Control Centres of all lines (1, 2, 3 and Tram) are fully staffed with at least 8 people per shift and operate 24/7 (even during night hours when only service trains are in operation).

Any individual technical problems in a network that continuously operates for 19 hours every day are handled immediately and are not connected in any way to safe passenger movement.

At the same time, both the network and the rolling stock are constantly expanding and streamlined. In the last year, there are 25 new and modern trains in the 2 tram lines, upgrading the transport provided.

The project for the upgrading of 14 trains of line 1 is under way and will be completed by June 2024.

Three years ago almost 50% of the three metro lines trains was immobilized due to spare parts shortages, but deliveries are normalized now. As a result, immobilized trains were repaired and returned to service. In line 1, trains that have been out of service for the last 7 years are returning to service, while metro lines 2 and 3 have been similarly enhanced, as 12 more trains have already been repaired and operate safely.

The safety systems are systematically checked every day, prior to putting the trains in service; the specialised technical staff and the operating staff follow all prescribed control procedures in order to ensure the highest possible passenger safety.

THE HUMAN RESOURCES OF STASY: STASY’s operating staff is well trained and experienced. Technical staff, electric train drivers, station masters, as well as employees at the Control Centres of all Metro and Tram Lines are trained and retrained in safety-critical items at regular intervals. By way of example, the retraining of the Metro Lines 2 and 3 technicians on track safety issues was completed in 2022 and the retraining of station masters will begin in 2023. In Line 1, 140 technical services staff and 20 train drivers were trained in safe work on or near tracks in 2022 and the training of 80 more electric train drivers is expected to be completed in 2023. In addition, train drivers are scheduled to be retrained on health and safety at work.

Train drivers, station masters and Control Centres staff undergo psychometric tests prior to the commencement of their duties. Every year, Metro and Tram train drivers, as well as all employees holding a train driving licence, undergo medical checks and psychological assessments.

In addition, the entry into force of the new institutional framework has put an end to staff transfers on the basis of the mobility system and allows for more flexibility in recruitment. In 2021-2022, a total of 319 recruitments were made, of which 169 were unfixed-term recruitments through ASEP, for the first time since 2009. 303 recruitments are scheduled for 2023.

TRAINING EXERCISES: Emergency measures taken due to the health crisis made it difficult to carry out emergency exercises. Nevertheless, exercises were carried out by the Fire Department at the Metro and Tram Depots in Sepolia and Elliniko in 2022 with the participation of STASY staff. The scenario of the exercises provided for the rescue of individuals and the training comprised both theoretical and practical aspects.


TRAIN MAINTENANCE: The trains that run daily are capable and safe to carry out transport. Their regular maintenance is carried out at the prescribed times by the staff of the STASY technical repair bases, who have the necessary know-how and experience. The spare parts used to repair technical failures are always procured by certified railway material manufacturers.

In Athens transport, security is a priority. For this purpose, when there are maintenance works, part of the fleet does not operate. This may result in longer intervals between service for some time, but ensures that all trains and vehicles used are in very good condition.

WARNINGS WITHIN TUNNELS AND EMERGENCY EXITS: The position of the light-signaling devices on the network of Line 1 have been determined and installed on the basis of relevant studies and any failures recorded during the daily operation are checked and restored. In case of emergency and shutdown of light-signaling devices, back-up safety lighting is automatically activated. In addition, along the only underground tunnel of Line 1, in the Monastiraki-Attiki section, there are emergency exit signs, which indicate by an arrow the nearest emergency exit and provide information about the remaining distance.


As regards the emergency exits in Line 1, they are also released manually by the trained staff of STASY, but they are also remotely controlled by the Control Centre. Thus, in case of emergency, they are all centrally released from the Control Centre and open in both directions (inside and outside) with a simple push. It should be noted that they are regularly checked and maintained.


We promote the cultural wealth of Attica and seize all opportunities to contribute to shaping the city’s identity.

The fleet

The company’s passenger fleet comprises:

electric railway trains (line 1)
metro trains (lines 2 and 3)
articulated tram vehicles

25 new ultramodern articulated tram vehicles were incorporated in our fleet in November 2021.

The network

Line 1

Piraeus – Athens – Kifissia


Line 2



Line 3

Dimotiko Theatro- Doukissis Plakentias – Airport

(In the Doukissis Plakentias-Athens International Airport section, metro trains make use of the Urban Railway passageway, which belongs to the national railway infrastructures managed by OSE)

Tram - 2 Routes

On 15.12.2021 two new lines were inaugurated and added to the existing Tram network, which replaced the previous ones:

Line T6 (Syntagma – Pikrodafni)

Line T7 (Asklepieio Voula – Aghia Triada)


The commercial operation of the Tram extension towards Piraeus comprises the operation of initially 11 new stops: “Karaiskakis Stadium”, ”Mikras Asias,  “Lambraki”,  “Evangelistria”, “Deligianni Square”,  “Townhall”,  “Aghia Triada”,  “Ippodameias Square”,  “34th Syntagmatos Pezikou”, “Androutsou”, and “Omiridou Skylitsi”.  The 12th station, “Akti Poseidonos”, will soon be delivered and will become the new terminal station of Line 7.
