Hello, it doesn't exist a project to reintroduce the trolley-bus. Actually in Dresden a Hybrid-bus of the label "Solaris" is been tested. The trolley-bus is too expensive, because you need a new infrastructur and a normal bus has the same capacity like the trolley-bus. In the next time the big "CapaCity" (that's the name of a big diesel-bus of Mercedes-Benz) will be tested again in Dresden. It visited Dresden some months ago. This Bus isn't much longer than a normal bus, but mor passengers can be transported with it. Trolley-busses in Germany aren't very popular and in danger of extinction.
In Dresden the bus-line 61 is our old trolley-bus-line. It is high frequented, but the CapaCity or an other big bus is cheaper for this line, because this line is mor than 25 km long, and 25 km catenary is too expensive. I think bis O-Busses like the ones in Zurich (Switzerland) are perfect for this route, but the price is too high. So a trolley-bus in Dresden is only a nice dream
