Buses paralleled tram lines, giving through service to passengers traveling longer distances. New trolley bus route extension was discontinued in 1959, and the service was gradually phased out. There have been recent reports of trolley bus service being reintroduced in Prague. Although an underground Metro system was envisioned for Prague in 1939, it was not until 1974 that the first Metro line was completed. Prague was in the 1 million population bracket at that time, and it was felt that a Metro was a necessity and perhaps somewhat overdue.
Additional construction is underway or planned.
There are also expansion plans for both the tram and bus networks in Prague. Its purpose is to coordinate transport in Prague. The decrease in the number of passengers is mainly the result of a recalculation of the trips, plus more automobiles being used by the public. Nevertheless, Prague Public Transit continues to carry 65 percent of passengers in daily trips within the city. Season tickets are most popular, and account for 75 percent of the income collected from passengers.
