In the public transportation systems of the Soviet Union, the only common use of turnstiles was at the entrance to subway stations (first introduced in Moscow Metro on November 7, 1958). City buses and commuter trains usually operated on the honor system. But as fare collection became a more pressing business in post-Soviet Russia, railway terminals and high-traffic railway station in the Moscow area, Nizhny Novgorod and elsewhere had turnstiles installed.
In the early 2000s, Moscow authorities went one step further in their quest to improve fare collection: since enclosing all bus and tram stops and providing them with fare gates would not be feasible, the authorities resorted to installing turnstiles inside each city bus and tram. This practice has caused numerous passenger complaints as it reduced the speed of boarding, compared to the traditional honor system. A similar system is in use in Brazilian city buses.
