Welcome to another brand new month of trolley-posting here at Twice-Weekly Trolley History! For the month of September, we have no real theme this time, but we hope the variety can keep you riders and readers interested!
The electric motor. The trolley pole. Air brakes. We all seem to take these things for granted when we stand back and examine what a streetcar is. After all, hindsight breeds common sense: it makes sense to us to have a stick reaching up and gathering electricity, which feeds a traction motor attached directly to an axle to move the car. But how did these elements come together in the first place? Why did this process work and not a rolling troller on a wire? And who, above all, profited from these patents? Well, dear riders, we have the answer to those queries on today's Trolley Tuesday and his name is Frank J. Sprague, inventor.
