Russia
This is a trolley bus service that for 10 rubles takes you all the way up (or down) Nevsky Prospect. The trolley buses whizz past so fast it can be hard to decipher the place names if you don't speak Russian but this service takes all the leg work out of Nevsky and means it is less stressful when trying to cross the street. Just wait at the bus stop and smile when boarding - it disarms the ticket collector and they are then generally helpful. There are others but this one is safe, fast and easy to use. Whereas the Metro isn't much help as it goes no further along than Gostiiny Dvor.
The trolley buses run frequently up and down Nevsky Prospect.
