The Bratislava public transport company DPB recently tested an 18-metre hybrid trolleybus in the capital and now it is testing one of the longest trolley buses in the world.

“We plan to address the ever-increasing passenger demand on route 201 by deploying longer trolleybuses,” the company wrote on its website.
The new double articulated, 24-metre vehicles should replace the existing 19-metre articulated trolleybuses. The similarly long vehicles already run in Linz and several Swiss cities.
“As we do not yet have experience with such long, large-capacity vehicles in Bratislava, before announcing the tender for the purchase of new vehicles, we approached several manufacturers with a request for testing,” the company informed, adding that it is testing a vehicle provided for the purpose by the manufacturer who responded positively to the request.
