Gent, Belgium gyrobuses Nos 1453 and 1452 at an intermediate charging point where contact was made to a three phase AC supply on a projecting arm via three spring booms on the roof of the gyrobus. Although not seen here the photographer suggests there were also two auxiliary contact arms that moved sideways from the gyrobus to make contact part way down the post.Buses sub page; Electric Buses
