The mass transit sector in a lot of African countries is served by private operators using diesel buses of varying capacities. These could range from 14-seater small buses/shuttle vans to 30- to 40-seater buses. Some operators also use higher capacity buses with the capacity to ferry over 60 passengers. Bus operators in this sector face ever increasing servicing and maintenance costs as well as high diesel fuel prices. This is one of the reasons why a strong focus is now being placed on electrifying this sector.
