Generally, people meet at a predetermined station in their city's mass transit system, wait until their numbers have achieved critical mass, and board the train.
The municipal mass transit system is the oldest one in present day Slovakia, with the first horse-car line beginning operation in 1891 (electrified in 1914).
After years of study, the construction of a non-polluting mass transit system was proposed; the trolleybus was chosen as the most appropriate means of transport.
