[1] In recent years, the system has shrunk, and most of the Soviet era trolleybuses have been replaced by newer vehicles.

Former deputy Mayor of Yerevan, Hrachya Sargsyan, stated that 101 new trolleybuses for new routes is planned.

Karapetyan swam to it and, under conditions of almost zero visibility due to the silt rising from the bottom, broke the back window with his legs.

The trolleybus was crowded, it carried 92 passengers and Karapetyan knew he had little time, spending some 30 to 35 seconds for each person he saved.
