New TROLLEY publication: handbook on diesel bus conversion

Together with the University of Gdansk and the Trolleybus Company in Gdynia (PKT) the TROLLEY partner City of Gdynia has published a comprehensive handbook for the conversion of diesel engine buses into trolleybuses.

As PKT was facing the problem of reconstructing rolling stock fleet by buying new expensive low floor vehicles, Gdynia developed a concept of building trolleybuses based on the coachwork of low floor buses coming from the aftermarket. The approach proved to be successful as PKT was able to renovate 5-6 trolleybuses a year, thereby rapidly increasing the number of low-floor vehicles in Gdynia. With the published handbook other operators now have the possibility to benefit from the experiences made in Poland.
