>>1212050The line where they introduced this is pretty short compared to the rest of the bus lines. It connects 2 metro terminals, one downhill and one uphill. And the wires are on a shorter section which makes about 1/3 of the line.
Still if the bus should be running the whole service as other regular buses (fast turns at end stations) and carrying bigger ammounts of people as usually. In other words, working in normal service, not some fancy useless electrobus line. Then it needs some more technology development and testing. Batteries are not so quickly charged as they should be and there is a charging needed at the terminuses. However it seems this is the way to go for Prague. Let's hope for some more trolleybus lines in a future.
See the map, wires are between stations Kundratka and Prosecká
