However, for long trips people use trains, buses, and metro. Public transportation is reliable and efficient. For example, there 6 metro lines and 39 metro stations with 1-1,5 km distance between them, and frequency is 4-6 minutes in peak hours. However, there are no metros after 00:30, so they are replaced with night buses. Speaking of the buses, in the daytime they cover rural places which are not covered by trains, and the buses also connect nearby towns and cities. All of these allow smooth travel across the city and other cities nearby
