With the total line length of almost  of a single wire, 8 depots, 104 routes, and 1740 vehicles, the Moscow trolleybus system was the largest in the world. But municipal authority, headed by Sergey Sobyanin, began to destroy the trolleybus system in Moscow in 2014 due to corruption and planned replacement of trolleybuses by electric buses. In 2018 Moscow trolleybus system has only 4 depots and dozens of kilometers of unused wires. Almost all trolleybus wires inside Garden Ring (Sadovoe Koltso) were cut in 2016–2017 due to the reconstruction of central streets ("Moya Ulitsa"). Opened on November 15, 1933, it is also the world's 6th oldest operating trolleybus system.
