Interesting article - cars displaced and interfered with streetcar traffic, the service was provided by private companies, and fares didn’t move with inflation.

As much as I like transit, I do think running trains in the middle of a street of traffic was a dead concept as soon as the automobile became available to most people. A dedicated lane with signal priority becomes necessary for safety and for capacity/speed. That, or they need to have right of way in the curbside lanes. Horses and pedestrians are a very different traffic problem.
