The term 'trolley' predates the invention of the trolley pole. The earliest electric cars did not use a pole, but rather a system in which each car dragged behind it an overhead cable connected to a small cart that rode on a 'track' of overhead wires. From the side, the dragging lines made the car seem to be 'trolling' as in fishing. Later, when a pole was added, it came to be known as a trolley pole.

  • The term 'trolley' predates the invention of the trolley pole. The earliest electric cars did not use a pole, but rather a system in which each car dragged behind it an overhead cable connected to a small cart that rode on a 'track' of overhead wires. From the side, the dragging lines made the car seem to be 'trolling' as in fishing. Later, when a pole was added, it came to be known as a trolley pole. The term trolley is also used to describe the pole or the passenger car using the trolley pole is derived from the grooved conductive wheel (trolley or troller) attached to the end of the pole that "trolls" the overhead wire. It was first used by an experimental tramway in Toronto, Ontario in 1883, having been invented by John Joseph Wright, brother of the mining entrepreneur Whitaker Wright. Modern "trolley cars" usually don't use the grooved trolley wheel at all, but use a grooved sliding "shoe" containing a carbon insert.
