The PSE began operations on September 25, 1902 with a line that started in downtown Tacoma, ran along Pacific and Puyallup Avenues, followed the course of present day Pacific Highway through Fife and to Milton, turned southeast towards Puyallup and paralleled the path of today's SR 167 through  Pacific, Algona, Auburn, Kent, Orillia and Renton, then into Seattle on its own dedicated right-of-way, via South Park, from there running on surface streets to the area near Pioneer Square, where it interchanged with other interurbans in the area.

Power was supplied via overhead wire in urban areas, and third rail in rural areas.
The third rail was the cause of several accidents throughout the PSE's operations which involved livestock or people being electrocuted, and in some cases dead cows caused accidents involving the trolleys themselves.

The railroad ran for 26 years, until competition from trucks, buses, and automobiles on an ever-expanding road network, as well as the steam railroads, led to reduced ridership in the early 1920s and a decision to shut down operations was made by the operators.
Despite protests, the interurban was allowed to suspend operations by a federal judge in a ruling made on October 13, 1928.
The final trains ran on December 30, 1928.
The rails were not pulled up until 1930.

It was headquartered in Kent, Washington.
