The time is counting down to make them available to the passenger public in the coming weeks electric buses in Athens and Thessaloniki. According to the contract for their supply, the new electric buses, type YUTONG E12 (140 in Athens and 110 in Thessaloniki), must have traveled 18 hours a day – without passengers – until they complete 5,000 km in daily traffic conditions.
Routes made with sandbags, weighing 2.5 tons, to simulate the weight of the passenger public, to get the “green light” and welcome passengers. At the same time, the installation of telematics and ticket validation machines has already begun, while the process for the installation of issuing machines is also underway, with the aim of issuing tickets with electronic payments within the cities.

The electric buses are 12 meters, 75 passengers. They charge in about three hours. Based on the competition specifications, they must have a range of at least 180 kilometers. However, until now the test routes have shown that the autonomy of the buses reaches 300 kilometers.
They have an air conditioning system, ventilation, tilting windows. They have a ramp for the access of Persons with Disabilities in the middle door and a special position for a wheelchair. They are ecological and zero emission and are silent.
Tests on the streets of Athens and Thessaloniki
“The electric buses are already being tested on the streets of Attica, as part of the supply contract, and they fully meet the high standards that have been set for their inclusion in the transportation project we are carrying out,” said the CEO of O. SY.A.E. Stefanos Agiasoglou.
According to OSY, the new buses have an Intelligent Bus Monitoring / Management System (ITS), namely:
Fleet management.
Fleet overview.
Live monitoring.
Route overview.
Resource management.
Charge management.
Monitor chargers.
Charge file.
Charge statistics.
Full reporting system.
Energy consumption report.
