Moderně řešené pro trolejbusy pro současná města (Modern trolleybuses for contemporary cities)
The electric trolleybus is a long established form of urban public
transportation. It had a heyday in the 1930s and 1940s as replacement for street
tramways. Its fortunes began to decline in the 1950s as diesels became as cost
effective and the 'inflexibility' of a fixed infrastructure became to be
perceived as a disadvantage. At that time, decreasing public transport ridership
was often just accepted as inevitable and environmental issues were of little
concern. As equipment wore out, many trolleybus systems were replaced by
diesels. Falling markets for trolleybuses and their equipment increased costs
and accelerated the decline.
Major oil supply crises in the 1970s reversed the process. Since then the need
to improve urban public transport and increasing awareness of environmental
issues have generated renewed interest in trolleybus technology. Existing
systems have expanded and re-equipped and new systems opened. The announcement
of a new trolleybus system for Rome and the opening of a new system in
Landskrona in Sweden are examples. Rome, which already has metro and tramway
systems, is investing in a 300 vehicle, 10 route trolleybus system, with off
wire operation in the city's historic centre. More
