The urban public transport system in Ukraine includes both trolleybuses and trams.
Trolleybuses run on the roads, like ordinary buses, which means they can fit into the existing road network with little need for restructuring. Unlike trolleybuses, trams run on specially constructed tracks and therefore require significant investments. However, trams have certain advantages compared with buses and trolleybuses. They can carry large numbers of passengers, have low running and maintenance costs, and offer a high level of passenger safety.
Neither trams nor trolleybuses have an internal combustion engine, making them less environmentally polluting.
