Trackless Trolleys or Trolley Busses Provide Cost Effective Service

The trackless trolley or electric bus was perfected in the 1930's. Many street railways in large cities, converted to these very economical vehicles. The biggest savings, were in not having to maintain the trolley tracks in the street anymore.

Like streetcars, trackless trolleys got their power from overhead electric wires. But, trackless trolleys were a little more flexible. They could pull into the curb to pick up passengers, and maneuver around double parked cars and other obstructions, because they didn't have to follow the rails.

Also in the 1930's, a hybrid version of the trackless trolley, came into use in some cities.  This combination trackless trolley, and gas or diesel-electric bus, was called an "all service vehicle".  All service vehicles were even more flexible than the trackless trolley.  They could pick up power from the overhead electric wires when they were in the city, like a trackless trolley.  When they reached the "end of the line" however, they weren't forced to follow the wires around a loop and start back to the downtown area.

With an all service vehicle, when the end of the overhead electric wires was reached, the trolley poles could be hooked down to the roof, and a gasoline or diesel engine could be started, which drove a generator, which generated the electricity needed by the electric motors, to run the vehicle.

This allowed an all service vehicle, to continue on a trip further out of the city, into the suburbs where there were no overhead electric wires.  When the all service vehicle, returned to the part of the route where overhead power lines were available, the trolley poles could be raised, to again collect power from the overhead wire, and save on gasoline or diesel fuel.

ACF-Brill, at one time one of the largest builders of streetcars in the country, also built trackless trolleys, or trolley buses.
