The line consists of two parallel tracks with one train riding each track. The fleet consists of two trains constructed by Alweg in 1961. These original trains are still in service and have served the line since its opening in 1962. Each train is powered by four 750 Hp DC Motors running at 700V and typically drawing up to 700 amps. The motors are controlled by a mechanical motor controller that adjusts the position of the motors and number of resistors in the circuit. The motors run into a standard truck differential, with one side blocked off and the other running to the driving wheel, which runs a standard truck tire.

The Westlake station of the monorail has an elevator down to the Westlake Station of the Downtown Seattle Transit Tunnel, a stop for the Central Link light rail line, and major Metro bus lines. Westlake Center is also near the southern terminus of the South Lake Union Streetcar and numerous surface bus routes. At the northern end of the line, the Experience Music Project building was designed so that the monorail passes through it on its way to the terminal.
