Perspektywa wykorzystania napędu alternatywnego w lubelskiej komunikacji trolejbusowej (2)
PublikacjaTrolejbus stanowi pośrednie rozwiązanie między autobusem a tramwajem. System klasycznej komunikacji trolejbusowej nie wymaga tak znaczących nakładów inwestycyjnych jak w przypadku tramwaju, lecz nie jest porównywalnie elastyczny ruchowo. Komunikacja trolejbusowa uzależniona od zasilania trakcyjnego stała się uciążliwa w eksploatacji. Poszukiwano więc rozwiązań umożliwiających „uelastycznienie” trolejbusów. W wyniku rozwoju technologii...
