The Crosstown car #61 route continued as a trolley on Manhattan ave a bit longer after the trolley buses came. Trolley Buses were used on the Graham ave line, The Lorimer street Line which ran up Nassau Ave in Greenpoint, and the Tompkins ave line which went from Bridge Plaza down to Ebbets Field.The trolley buses went into service in 1949. When the Pulaski Bridge replaced the Manhattan ave double bascule, Buses were used to cross that Bridge to go to Long Island City. The Graham ave trolley bus did not cross the Brooklyn Bridge as the predecessor trolleys did.
Here is a Trolley Bus on the Lorimer street route. I believe this photo is at Nassau Ave and Manhattan ave.
