Bus #1005 at Cortelyou Road and Ocean Parkway, date unknown.

In 1930 the trolley route along Cortelyou Road became one of the first test routes of the "trackless trolley." These vehicles were electric buses that drew power from overhead wires (seen here coming off the top of the bus and attached to the overhead lines above the back of the bus). These types of vehicles operated in Brooklyn through the late 1950s, meaning they were on the road at the same time as traditional trolleys, gas-powered buses, and both underground and elevated trains.
